Supernova

Hi Lithopsian,

Thank you for your contributions to the Supernova article. Following your changes I made certain revisions in order to comply with Wikipedia policies such as WP:LEAD and, most importantly WP:CITE. If you have reliable sources for some of your additions, it would be appreciated if you could add them in. I'd like to keep the article at WP:FA status, if I could. Regards, RJH (talk) 14:24, 1 June 2012 (UTC)

Your recent edits

Hello. In case you didn't know, when you add content to talk pages and Wikipedia pages that have open discussion, you should sign your posts by typing four tildes ( ~~~~ ) at the end of your comment. You could also click on the signature button or located above the edit window. This will automatically insert a signature with your username or IP address and the time you posted the comment.

Welcome to Wikipedia. Everyone is welcome to contribute to the encyclopedia, but when you add or change content, as you did to the article Eta Carinae, please cite a reliable source for your addition. This helps maintain our policy of verifiability. See Wikipedia:Citing sources for how to cite sources, and the welcome page to learn more about contributing to this encyclopedia. Thank you. Also, if you want to replace citations or remove large amounts of text, you should discuss it on the article's Talk page, first. — UncleBubba ^{( T @ C )} 23:59, 10 June 2012 (UTC)

Massive reversions

You might want to turn on "TWINKLE" ( http://en.wikipedia.org/wiki/Wikipedia:Twinkle ) to help undo massive reversions like we just saw from an IP address onto VY Cygni. With TWINKLE enabled, when you do a compare of a bunch of edits done by a single user, you will see in the top part of the comparison page a set of "rollback" options, which will undo all of the edits in question. Massive saving in labor. — Preceding unsigned comment added by Tarlneustaedter (talk • contribs) 18:44, 25 July 2012 (UTC)

Thanks, I messed up that last change by only reverting one of four changes and then making another edit to the article.

Other possibility is Rollback privilege ( http://en.wikipedia.org/wiki/Wikipedia:Rollback_feature ), which is built-in to Wikipedia, and offers you a [rollback] button next to the edit history. But takes some time requesting the privilege, may or may not be worth it if TWINKLE works for you. Tarl.Neustaedter (talk) 19:00, 25 July 2012 (UTC)

Verification of the references provided for the claim...

that "NML Cygni is the largest star known" and "has 6500 times that of sun"

First of all I want to thank you for providing this information about NML Cygni to the article List of largest known stars. The article on NML Cygni has been nominated for Wikipedia:Did you know. If accepted this would be featured in the main page. It is located at Template:Did you know nominations/NML Cygni

But the references must be checked for accepting it. Hence, at the time of reviewing this should be verified. But only the abstract of this source ([1]) is visible to everyone. Access to full view requires permission. You might have access to the full view. So, can you please help me in solving this problem. Thank you. ···Vanischenu^「m/_Talk」 00:56, 28 August 2012 (UTC)

And can you tell us from where we can get an image? There are some good images Columbia University's paper, but most probably we can not use those. I have not found any image in Nasa galley! You can reply here: User_talk:Vanischenu#Talkback_on_23_August_2012 --Tito Dutta ✉ 15:42, 28 August 2012 (UTC)

This was to be featured in the Main Page of Wikipedia. So is there any way you can support the claim with a reliable source. We will be in trouble then and also note WP:verifiability, not truth. If we do not have a materials to support this, then we will have to cancel it. ···Vanischenu^「m/_Talk」 18:02, 28 August 2012 (UTC)

Most luminous stars

Thanks for the comments. Formerly, the entry for Betelguese didn't have anything at all under absolute magnitude. So even if the figure is slightly off, it's still better than what we had before. If it's incorrect, my hope is that someone would fix it, and at the same time fix the starbox on the Betelguese page, which is where I got the data. On the Rho Cas page, the distance was recently changed from 12,000 LY, so that's why I changed it on this page. For the more casual observer, VV Cep appears as a single point of light having a mag. of 4.91, so again, I think that entry is an improvement over what we had before (which was nil). But if someone wants to elaborate on the fact that that's actually a combined magnitude, of course they may. Niobrara (talk) 18:39, 12 September 2012 (UTC)

Eta Carinae

You sure you got the right edit here? Your summary doesn't match what you changed (no reference changed), and for a summary to be clear about where something is makes sense (out of context, I might think of Victoria, BC). Tarl.Neustaedter (talk) 00:50, 24 October 2012 (UTC)

Copernican principle

Lithopsian: Just using "Revert without reading is wrong. As we are all informed when given status as a reverter, that power is to be used sparingly, and only when it is plainly vandalism or similar behavior. That last edit you reverted was at least a good faith edit, and if it merited being undone, you should have done it that way, and specified a reason.

Rolling back a good-faith edit, without explanation, may be misinterpreted as "I think your edit was no better than vandalism and reverting it doesn't need an explanation". Some editors are sensitive to such perceived slights; if you use the rollback feature other than for vandalism (for example, because undo is impractical due to the large page size), it is courteous to leave an explanation on the article's talk page or on the talk page of the user, whose edit(s) you have reverted."

Go slow on reverting, even though the the tide seems to be rising. Happy editing. 7&6=thirteen (☎) 11:49, 5 April 2013 (UTC)

(edit conflict) Bold reverting won't work - we have to read their arguments and reply, on talk or/and edit summaries. They sometimes use unreliable sources or re-interpret the sources - those edits can be undone (not reverted). If edits don't have obvious flaws then any editor should watch out for edit warring. Regards. Materialscientist (talk) 11:54, 5 April 2013 (UTC)

Ditto. 7&6=thirteen (☎) 12:11, 5 April 2013 (UTC)

I assumed (perhaps wrongly) that you were a "rollbacker". This is sometimes very useful, and you might want to make a request. That was the occasion for my getting the lecture. 7&6=thirteen (☎) 12:38, 5 April 2013 (UTC)

The Wikipedia concept is that these articles are debated and controversies (including WP:RS) are vetted on the talk page. Hopefully, this will make them better. We are to WP:AGF. And to work this through, e.g., WP:BRD. When one projects the image of WP:Own in a particular article, this can invite the misguided "hiding the truth" sobriquet. The process can be sometimes ugly and frustrating, to be sure. Please excuse my intermeddling. Just food for thought. Cheers. 7&6=thirteen (☎) 13:10, 5 April 2013 (UTC)

Google cache

Hi, Lithopsian. You were the first person to post the link to "The Principle" working group forum, that I blocked Wyattmj over — this link. It's a Google cache link, so I don't really get how it can now be a 404. But it is. Do you think that's just some temporary glitch? Or can it be found in some other way? I have to ask ask, as I'm not good at this stuff. Bishonen | talk 14:07, 11 May 2013 (UTC).

Cached Google pages do sometimes disappear for a while when they are getting updated, but this looks different. I suspect the website owner has requested Google not to show the page, something that any webmaster can do for private content. If so, the "cached" link on Google search results for that page will eventually disappear, and presumably we will then be accused of a conspiracy. So we can't currently see the page that Noleander luckily quoted for us. However, other pages from the same discussion and other discussions at the forum can still be seen. Here is a Google search of posts at that board about Copernican, you can view the cached image of most of them. This one seems to be the original idea that marking up Wikipedia needs to be part of their advertising campaign. This is page 1 of the post I originally link.

That's extremely helpful. Thanks very much. Bishonen | talk 11:10, 12 May 2013 (UTC).

68 Cygni revisited

Hi, you seem to know what you're talking about when it comes to massive OB stars, so would you mind having a look at 68 Cygni so that I can be sure that there are no factual errors or misrepresentations in the "properties" section? I plan to bring it to GA sometime, where the reviewer might not be knowledgeable about astronomy, so such a check would be very helpful. StringTheory11 (t • c) 02:45, 18 December 2014 (UTC)

HD269810

I have noticed that on the case of HD 269810 you said that the magnitude was -6.6, but the real magnitude is -11.1. I can prove this to you because each magnitude of 1 corresponds to a change in brightness by a factor of 2.5. So we know that the sun's magnitude is 4.83 so 4.83+11.1=15.93 and 2.5^15=(approx) 2.18 million times brighter than the sun. This corresponds with the luminosity of HD 269810 which is 2.2 million times brighter than the sun. — Preceding unsigned comment added by I am. furhan. (talk • contribs) 01:00, 4 January 2015 (UTC)

You should listen to I am. Furhan. His facts are correct while yours are not.--Gangoose (talk) 01:08, 4 January 2015 (UTC)Gangoose

Furhan, you're thinking of bolometric magnitude, which is the total electromagnetic radiation given off by the star. The infobox field is for the V-band magnitude, which is roughly how humans see the star. The difference is due to the fact that the star emits most radiation in the ultraviolet, so it is brighter bolometrically than visually. StringTheory11 (t • c) 01:49, 4 January 2015 (UTC)

Plus, and I'll say this again because you haven't taken it on board from all the previous times: the referenced paper *states* that the absolute visual magnitude (M_V) is -6.6. I did not have to calculate, mis-calculate, or otherwise synthsise to reach this number. I suggest reading WP:NOR thoroughly before you post anything else. In this specific case, it is *never* appropriate to calculate M_V for yourself; you don't have enough information and if you think you do then you need a couple more years education before editing articles about stars. Bolometric luminosity and bolometric magnitude can be considered equivalent and it may be acceptable to convert between the two, but still better to find a peer-reviewed reference that gives you an actual number. Lithopsian (talk) 15:24, 4 January 2015 (UTC)

Also how strange that a new user with no edits before this pops up to say Furhan is correct... StringTheory11 (t • c) 01:50, 4 January 2015 (UTC)

Agreed. There have been an intriguing number of edits and undos with the same overall "look and feel" under different identifiers. While edits appearing under one or several different IP addressees may be a perfectly innocent failure to log in, it can give an aura of suspicion. Posting under different user names, even getting your friend to create an account just to support you, is a serious violation of Wikipedia policy. Don't ever do it or you will get banned. Lithopsian (talk) 15:24, 4 January 2015 (UTC)

Why is the death part on HD 269810 wrong? — Preceding unsigned comment added by I am. furhan. (talk • contribs) 00:31, 9 January 2015 (UTC)

Well the biggest problem is that you gave no references at all, so it just amounted to your opinion. If you gave a reference that said that the star would die as either a hypernova or a gamma-ray burst then it would probably still be there. My personal understanding is that (what I remember of) what you wrote is also factually incorrect. The first thing is to drop your obsession with pair instability supernovae, because this star isn't going that way. The theory suggests that they simply don't occur in the local universe because metallicity is too high. Any statement about what sort of supernova will result needs to be hedged, because we simply don't know. There are theories of massive star evolution into supernovae but they are known to be inaccurate because they don't simply don't match observations. This extends to gamma-ray bursts which are *theorised* to result from *some* supernovae of type Ib or type Ic (or both), but almost certainly not all. This is all in the context of zero reliable observations of the progenitor of a gamma-ray burst, let alone observations of a hypernova or pair instability supernova progenitor. Still, forget what I think I know (or what you think you know) and just describe what the best available research says. Preferably specific to this star, because trying to guess for yourself which model might be applicable to this star is getting dangerously close to own research. You might have to do that if nobody has described the likely end for HD 269810, but do so in only the most general terms and "show your working" :) References, references, references.

Comment for message

First of all, thank you for leaving a message on my talk page. It is indeed a very helpful subject. But anyway, next time please add a new section if you want to comment.

Regarding that case, as of R136a1 seems a bit very complex thing. The luminosity of 8.6 million Sun is incredibly high. Using the formula for density and the Stefan-Boltzmann law, the star is 80% of its Eddington luminosity, which in that case, it would be a turbulent LBV. But the spectrum shows differently, so I suspect that the star is binary, or there is an error.

R136a1's luminosity is not 8.6 million L,it is 7.4 million L.--I am. furhan. (talk) 16:30, 9 January 2015 (UTC)i am. furhan.

About WR25, it makes me dumbfounded when I saw it in the introduction in the Carina Nebula with the claim being the most luminous star in the galaxy. I doubt it very much. Nearby Eta Carinae is more prominent. Also, the luminosity of 6.3 million is beyond its Eddington, and a magnitude of 8.8 from 8,000 ly gives me 3,000,000 Sun, half of the suspected value.

It is a binary and you are forgetting about interstellar gas and dust cloud absorption.--I am. furhan. (talk) 18:16, 9 January 2015 (UTC)i am. furhan.

I myself never heard of BAT99-116. That is a very new candidate, although I found out that it is a binary. So I don't think the 8 million Sun luminosity is correct. SkyFlubbler ^(talk) 12:17, 9 January 2015 (UTC)

R136a1

This is my reply for "recent undo of recent edits"

@Lithopsian

@SkyFlubbler

I apologise for this. Maybe I was a bit to eager to expand the article so I didn't look into the details. Looking into the article, I find that it is poorly constructed, so perhaps you and me could expand this article and improve the content as you did with these edits to Eta carinae ([4] [5]). We should try to improve this article because this is a chief discovery in astrophysics. UY Scuti is important as R136a1 in astronomy, yet the article is well-written. Perhaps it is a matter of references, (UY Scuti's ref's mentions all of its properties) but we could try to pierce whatever we've got into a good article. We could also get SkyFlubbler into this because he is a good writer. (and when you reply, please leave it at my talk page) 142.177.125.72 (talk) 17:15, 12 April 2015 (UTC)I am. furhan.

The eddington limit section says, " In practice the theoretical Eddington Limit must be modified for high luminosity stars and the empirical Humphreys Davidson Limit is derived" That says that the eddington limit must be modified for high luminosity stars, i.e R136a1.142.177.125.72 (talk) 17:15, 12 April 2015 (UTC)i am. furhan.

Can you tell me what is wrong with the surroundings section on R136a1? As far as I know, I didn't copy it from any article. I wrote the draft of it on a piece of paper. Also, I checked the Tarantula nebula and R136 articles and I didn't see any of my text there.hi (talk) 16:44, 20 April 2015 (UTC)

I am. furhan. You were stoned when you wrote this, I'm assuming? "none of the member stars are significantly evolved and none are thought to have exploded as supernovae", word for word in both articles. Minor rewording of "Its luminosity is so great that if it were as close to Earth as the Orion Nebula, the Tarantula Nebula would cast shadows.", "The estimated mass of the cluster is 450,000 solar masses, suggesting it will likely become a globular cluster in the future", and "if it were as close to Earth as the Orion Nebula, the Tarantula Nebula would cast shadows" All of which is irrelevant. I don't care if the words came to you in a vision from God, the sentiments don't need to be repeated in an article that isn't even about that object. Say what needs to be said about the Tarantula and R136 in relation to R136a1, probably just a sentence or two, and leave the rest behind a link. Lithopsian (talk) 20:45, 20 April 2015 (UTC)

Is E135 a typo (meant to be R136)? See [change] . Tarl.Neustaedter (talk) 02:01, 21 April 2015 (UTC)

Can you go over R136a1 and remove any errors from it? Whatever you remove, I won't go and put it back. hi (talk) 14:24, 24 April 2015 (UTC)

eta carinae

On the eta carinae article, it says that the great eruption increased the luminosity by a factor of 10 which would make the luminosity 50,000,000L_☉, but it says in another place that it was 25,000,000L_☉. Also, the was a press release that said eta carinae's mass is 90M_☉ and that study took place in August 2014 so it would be more reliable than the other ref.I am. furhan. (talk) 18:47, 30 March 2015 (UTC)i am. furhan.

Check this. It says Eta carinae's luminosity is ~4,000,000 L_☉.

Does it? I beg to differ. Read the paper instead of just pulling out the first number you find. Lithopsian (talk) 20:49, 25 April 2015 (UTC)

Eta Carinae light curve

Great light curve images here; very helpful! Just one minor thing: in the 1987-2014 image, the R- and I-magnitude colors are very similar, and I was not easily able to distinguish the two at first. Maybe change the the R to a more maroon color? StringTheory11 (t • c) 18:59, 28 April 2015 (UTC)

R136a1 demotion

You demoted R136a1 from B class because of "Significant errors and contradictions (I removed the worst and tagged many others), a bit sparsely cited, difficult grammar to read." I can understand that.

• About the sparse citations, that is my fault, so I will try to dig up what I can find. I know a lot of citations that I could have used so I will go and add them.

• I don't really know what some of the errors are. I'm not a particular expert in the subject matter. I'm a 12 year old, and am self educated (in astronomy), so I probably will not be able to spot the errors. However, I will be able to spot the ones that you tagged, so I will try to find the refs on that. Once I am finished, I will tell you.

• I apologize for the plagiarism. I had made a different version on my sandbox, but that was really messed up (bad grammar, incomplete information). Anyway I have corrected that, so it is fine (although the grammar is still pretty bad)

• I probably will not be able to correct the grammar so this is up to you.

• I will comment on the part that you deleted in "evolution" in the sections below.

• • About this, maybe you could put that part back and, instead of deleting it, reword (or just add your own words) it so that it will make itself clear. Also, there is a study which we could use to expand the parts on WNh stars. Also, some of the information in the article contradicts the info in that paper, for example, the fact that it said WNh stars stay on the O sequence for a few thousand years, but the ref said that they turn into WNh stars when at the top of the main sequence. (which is probably after <~2 Myr.)

• • About this, I have a comment to make. R136a1 is presumably 80% of its Eddington limit, so 8.7 million ÷ 8 × 10 = 10,875,000, or its Eddington limit. Now, the 80% of its Eddington limit was derived by Crowther in this publication, so they would be using the value of 265 M_☉ and 8,700,000 L_☉. The current luminosity (using the value derived by hainich) is irrelevant here, but I calculated It to be around 65-70%. (Actually, I got a value of 68% which corresponds to a luminosity of 7,395,000 L_☉. Now, this value should differ from the actual value because; The mass is between 256-265 M_☉ (and some studies claim that it is even as high as 286 M_☉), and the value I got was below 7,400,000 L_☉. Anyway, this value should be close to the actual one.)

Now, at its birth, the star was 320 M_☉ so its Eddington limit would have probably been 13 million L_☉ (I don't know for sure, but did some rough calculations). 55% of 13 million is 7.1 million, which was probably its luminosity then. I'm not saying that we should put these numbers in, but just change the wording. (For example, we could say, "The star was probably over half as luminous as its current luminosity at its birth." etc.)

I've now covered the sections that you deleted so now I will move on to its promotion. As I said in my earlier statement,

"I apologise for this. Maybe I was a bit to eager to expand the article so I didn't look into the details. Looking into the article, I find that it is poorly constructed, so perhaps you and me could expand this article and improve the content as you did with these edits to Eta carinae ([6] [7]). We should try to improve this article because this is a chief discovery in astrophysics. UY Scuti is important as R136a1 in astronomy, yet the article is well-written. Perhaps it is a matter of references, (UY Scuti's ref's mentions all of its properties) but we could try to pierce whatever we've got into a good article."

The "refs that we could pierce together" that we got are mentioned here ([8] and [9]) and here. There is also a paper in prep that might be interesting.

Me and you could try to make this a project and improve it. Please reply to me and share your ideas on this.

I will now log off Wikipedia for the day. I probably should be finished cleaning up R136a1 by the end of the week and will notify you if I finish. hi (talk) 01:31, 13 May 2015 (UTC)

The mass of Westerlund 1

I think the statement about its mass might have come from here: http://www.dfists.ua.es/~ignacio/wd1_research.html - although this page only says it's the most massive young cluster in the Milky Way. This page (http://arxiv.org/abs/0711.1624) is for a paper co-authored by Ignacio Negueruela, who is responsible for the other page and it says Westerlund 1 is "among the most massive young clusters in the Milky Way". Perhaps this last statement could be included?VirtualDave (talk) 07:35, 9 June 2015 (UTC)

Probably. Someone got over-excited though. Even the (very old, in this context) web page only says "It is probably more massive than any other young cluster in the Local Group of galaxies." and that is an exaggeration of what they were prepared to put in a journal paper, which started as "likely to be one of the most massive young clusters in the Local Group" in 2003 and moderated to "among the most massive young clusters in the Milky Way" by 2008. If it is in a peer-reviewed journal and not refuted by more recent research then it can go in the article. We should be careful not to exaggerate, which usually means not relying on blogs, web pages (even of professional researchers!), and press releases, and not to state as fact information which is disputed or obsolete. Here's a fairly recent summary of young cluster masses in the local group, to provide some context: http://arxiv.org/abs/1002.1961 Lithopsian (talk) 09:02, 9 June 2015 (UTC)

Thanks. The paper you referred me to says on page 20 "Currently the most massive young cluster known in our Galaxy is Westerlund 1", although the authors qualify that by pointing out that it's easier to observe than some other clusters. I think that with things like this it's safer in Wikipedia to say "among the most massive" because they could find something bigger tomorrow, if they haven't already! I'll put in the sentence "It is among the most massive young clusters in the Milky Way". Towards the bottom of the Wd1 article there is a sentence which ends "how such a massive cluster formed", and so I think would read better if the fact that it is so massive was mentioned earlier on. I'd also like to look into the sentence "In the future, it will probably evolve into a globular cluster" - "probably" sounds a bit too strong to me. Let me know if you have any thoughts on it.VirtualDave (talk) 09:41, 9 June 2015 (UTC)

Beta Cephei variable

What I'm using for the table in the Beta Cephei variable article is the AAVSO data for β Cep variables. Do you think their data is not reliable enough to use in the article? StringTheory11 (t • c) 23:44, 3 August 2015 (UTC)

@StringTheory11 Apparently not. At a minimum, it would need to be cited, but it isn't exactly a peer-reviewed citable source. I don't know where they get their data from. Usually from the GCVS, but in this case it doesn't really match up. Sometimes there are citations in the VSX page, but they're often old or not relevant. Stankov is the most recent comprehensive source I could find, but there may be a handful of updates since then. Both Stankov and GCVS can be queried online. Also try this one, could have some stars that Stankov missed or rejected, and cites other fairly recent sources. Lithopsian (talk) 00:03, 4 August 2015 (UTC)

Thanks, I'll keep that in mind. Whenever I work with individual star articles now I never cite databases anymore for precisely that reason; I'll attempt to extend that practice to lists. StringTheory11 (t • c) 01:46, 4 August 2015 (UTC)

Do you by chance know of a similar paper or the like for the Alpha Cygni variables? I'm interested in doing something similar there, but I had no luck finding such a paper on the ADS. StringTheory11 (t • c) 21:33, 11 August 2015 (UTC)

van Genderen did a series of papers in the 1990s. It isn't easy to extract a simple narrative from a series of rambling papers about all sorts of variable supergiants, but I'm not aware of anything much in the way of a comprehensive review since then. Lithopsian (talk) 22:15, 11 August 2015 (UTC)

Editing Bright Star Page

It is clear from your recent edits on the List of brightest stars page that you don't comprehend the edits you are doing. The magnitude of these stars is visual magnitude or 'v', not 'V' magnitudes which are photometrically obtained. Just presuming that the magnitudes are quoted all from SIMBAD, assumes that all the magnitudes are from the same source. They are not. I.e. Magnitudes should be quoted from the Yale Bright Star Catalogue V5, which are visual magnitudes. You need to either discuss/ persuade that another magnitude system should be used, and change all of them, not just because you 'think' they might be right. (as said in your reason to revert.) You have already erroneously assumed that variable stars were mean magnitudes, when in fact they were at maximum brightness as I conclusively proved before.

I also was in the middle of an edit when you again reverted the page, which is not very conducive in solving issues like these. (Note dual edits to revert pages is counted as 3RR if you are maintaining a position.) Consider your position before editing this page again, and formally discuss this on the talk page. Thanks. Arianewiki1 (talk) 15:17, 16 August 2015 (UTC)

Why are you bringing 3RR threats to my talk page? There is only one person who has made three reverts on that article, and it isn't me.

And what is all this about the Bright Star Catalog? There is nothing in the article about that, or about a particular photometric system being required. You're just making it up. I'll take your ideas to the correct place, but I have no clue where you get this stuff. Lithopsian (talk) 20:50, 16 August 2015 (UTC)

Blue Cone Monochromacy

Hi Lithopsian, thank you for your advices. I'm going to remove the content of 'blue cone monochromac'. When I recently submitted the new article of my SandBox the answer I received from the editor Anarchyte was "Thank you for your submission, but the subject of this article already exists in Wikipedia. You can find it and improve it at Blue cone monochromac instead". I thought, and now I understand that it was a mistake, that the editor was requesting me to put the content inside this page with the tiny change in the title. I'm going to immediately remove my content from there.

Then my question is: 'Blue Cone Monochromacy' is a human disease, also known as 'Blue Cone Monochromatism' and there is an entry on wikidata for it https://www.wikidata.org/wiki/Q18553394 but not a wikipedia entry, other than a redirect to 'Monochromacy'. 'Monochromacy' is not a disease, https://www.wikidata.org/wiki/Q450059. Do you think it will be better to ask on the talk page of 'Monochromacy' in order to know if editors would like to consider my sandbox article ? In my family there are many people with this disease, I often use Wikipedia and it is strange to me to don't see this disease inside wikipedia. — Preceding unsigned comment added by Renata.sarno (talk • contribs) 16:16, 28 February 2016 (UTC)

calculation of the radius of NML Cygni

hello Lithopsian, you helped me some time ago with regards to NML Cygni, therefore I'm addressing you again:

• First I've got a question. on the talk page of NML Cygni you said: The radius is not calculated from the angular radius. As explained in the paper, 16.2 mas is not a directly measured value. It was derived from assumed values of the temperature, luminosity, and distance. 1,650 is a rounded value for the most likely physical parameters given in the reference (3,250K and 270,000 L). I was wondering, is there an article in the en.wiki or somewhere else in the net, that explains how exactly the radius of a star is calculated based on the (estimated) stellar parameters. The reason is I'd like to mention the calculation of the radius on the de.wiki, because you're right, people (including myself) are obsessed with the largest, the most massive and so on and I think it is important to highlight the fact, that all radii are calculations based on estimated values.
• Second I'd like to ask you a favour, if you can spend the time. This article http://adsabs.harvard.edu/abs/2004ApJ...610..427Z is used as reference in the de.wiki for a calculated radius of 3700 for NML Cygni. Can you check if this is true, because it would make NML Cygni the by far largest known star. Thanks a lot. --Agentjoerg (talk) 07:02, 3 April 2016 (UTC)

Bad Faith / Edit Warring

Hello, I'm Arianewiki1. I noticed that you made a comment that didn't seem very civil, so it has been removed. Wikipedia needs people like you and me to collaborate, so it's one of our core principles to interact with one another in a polite and respectful manner. If you have any questions, you can leave me a message on my talk page. Thank you.

You currently appear to be engaged in an edit war. Users are expected to collaborate with others, to avoid editing disruptively, and to try to reach a consensus rather than repeatedly undoing other users' edits once it is known that there is a disagreement.

Please be particularly aware that Wikipedia's policy on edit warring states:

1. Edit warring is disruptive regardless of how many reverts you have made.
2. Do not edit war even if you believe you are right.

If you find yourself in an editing dispute, use the article's talk page to discuss controversial changes; work towards a version that represents consensus among editors. You can post a request for help at an appropriate noticeboard or seek dispute resolution. In some cases it may be appropriate to request temporary page protection. If you engage in an edit war, you may be blocked from editing. What's Bad Faith and edit warring? said DerrickMa502

Quick Solution to Current List of Bright Stars Issue

@Lithopsian My apologies for the last few posts, but trying to understanding your point of view is getting frustrating. Let's immediately and quickly fix this issue by putting it behind us, because I too have other edits and stuff to do... (like adding another seven stars to the List of brightest stars to tally them to 100 stars.)

I did happen to reread this "User:Arianewiki1 wanted all magnitudes to be clearly referenced and to come from a single source, preferably the Yale Bright Star catalogue (or FK5, but that is a non-starter). Nobody objected." mixed with some of the unnecessary rhetoric...

Q1. Do you Lithopsian actually object to using the Yale Bright Star Catalogue V5?

I also later said;

"The source of these magnitudes was taken from the USNO's Astronomical Almanac [10], which has a list of bright stars and their positions. If you bothered to look page L14 under "Section H:Stars ans Stellar Systems" it says of the 1467 stars listed; "all stars of visual magnitude 4.5 or brighter, as listed in the fifth revised edition of the Yale Bright Star Catalogue (BSC). I know this to be true, as the once missing No.63 β Auriga Beta Aurigae / Menkalinan 1.9 magnitude isn't included. (I fixed this on 18 June 2015, myself.) It is not in the FK5, because the star is a variable. (Most of these magnitudes also appear in the Fifth Fundamental Catalogue (FK5) Part I (Fricke+, 1988) (FK5), which had a revised edition in 1991.) The BSC V5 is mostly used because the magnitudes are consistent in both hemispheres of the sky. (The only useful 'update' is HIP magnitudes, which is also within the FK6, etc. This has the advantage of not suffering from atmospheric effects, which have to be properly accounted for in photometry.)"

Q2. Do you Lithopsian object to using the magnitudes in the 2015 USNO's Astronomical Almanac [11]?

Q3. As most of the star magnitudes quoted in USNO's Astronomical Almanac also appear in the Fifth Fundamental Catalogue (FK5) Part I (Fricke+, 1988), do you object to quoting both of these as reference sources in the List of brightest stars page?

Q4. Do you know of any other consistent magnitude listings better than the BSCV5 or FK5?

(Note: HIP photometry is good, but is not precisely 'V' magnitude. I don't know of any other sources that are acceptably recent.)

Thanks.

Edit Warring

You currently appear to be engaged in an edit war, as you have done here.[12] Users are expected to collaborate with others, to avoid editing disruptively, and to try to reach a consensus rather than repeatedly undoing other users' edits once it is known that there is a disagreement.

Please be particularly aware that Wikipedia's policy on edit warring states:

1. Edit warring is disruptive regardless of how many reverts you have made.
2. Do not edit war even if you believe you are right.

You can post a request for help at an appropriate noticeboard or seek dispute resolution. In some cases it may be appropriate to request temporary page protection. If you engage in an edit war, you may be blocked from editing.

Comments:

Furthermore, by stating "I have given up engaging with Arianwiki1 since that author has been repeatedly abusive to me, making demands, chasing down my edits, and simply being difficult where it would be easier to be helpful." This is avoiding WP:GF which is clearly sanctionable. You were properly requested to "Justify these statements properly, or they will be removed under Wikipedia adopted policies." More than a month had past, and you refused to engage in gaining consensus. You did nothing. I do suggest you read the Edit Warring warning above, as you have already avoided; "The article's talk page to discuss controversial changes." You just haven't done this. This is why I reverted your edit.

However, as you did here, [13], in this my comment [14], you also tried falsely accused me of producing "Remove fluff sentence originating from non-neutral editor (User:WAFred))"[15] As I stated, "This edit in question can be construed as a derogatory comment under WP:PA". This was made worse but justifying this under a fictitious User: (User:WAFred). Arianewiki1 (talk) 13:30, 22 April 2016 (UTC)

There you go again. I've asked you not to come here making threats and demands, but still you can't resist. You take everything as a personal insult, even edits that had nothing to do with you. Your only response to any edit to an article that doesn't 100% meet your own personal idea of perfection is to reverse it, never to improve it. I find it impossible to have any useful discussion with you. If this is unacceptable to you, then the simplest answer is not to come to my talk page making further threats and demands. BTW, edit warring takes at least two people. Lithopsian (talk) 14:18, 22 April 2016 (UTC)

Eh? " I've asked you not to come here making threats and demands,..." What "threats" and what "demands"? There are actually none within the statements above - and stating Wikipedia policies cannot be in anyway be construed as a threat. Actually under WP:AVOIDYOU "Accusing someone of making personal attacks without providing a justification for your accusation is also considered a form of personal attack." As for the WR31a page I still count 27 mistakes, and there are 11 sentences now all uncited. Even the given references are misquoted, and show the complete distinct lack of necessary knowledge and wisdom. That's no "threat" - that is the cold facts!

This is the wrong question. Other pages, for good or bad, don't change the reasons why yours keep getting deleted. I have a website, but that doesn't mean I'm entitled to a Wikipedia page. I also have a company, and that doesn't automatically get a page either. Just being a legitimate company doesn't affect whether it is notable or not. When Time Magazine puts me on the cover, then I get a page :) Also I'm not the one you need to persuade. I'm not likely to be the next person to review one of your articles, so the article needs to stand on its own merit. Articles about companies, legitimate or not, that are not notable enough to need a Wikipedia article are effectively just free advertising, aka spam. A couple of admins have already pinged you on this so be very careful. BTW, I'm not an admin, just an editor that checks through new pages from time to time, flagging up (or not) when they need a bit of work, a lot of work, or just getting rid of.

DYK for Chi Cygni

On 10 July 2016, Did you know was updated with a fact from the article Chi Cygni, which you recently created, substantially expanded, or brought to good article status. The fact was ... that Chi Cygni is a variable star that is over 10,000 times brighter at its maximum than at its minimum? The nomination discussion and review may be seen at Template:Did you know nominations/Chi Cygni. You are welcome to check how many page hits the article got while on the front page (here's how, Chi Cygni), and it may be added to the statistics page if the total is over 5,000. Finally, if you know of an interesting fact from another recently created article, then please feel free to suggest it on the Did you know talk page.

Your edits at V399 Carinae

You have failed to respond to another editor (Arianewiki1) regarding your edits at Talk:V399 Carinae, for almost three months. It would be highly appreciated if you could try to take the time to comment there, as soon as possible. Thank you for your anticipated cooperation. — Coffee // have a cup // beans // 09:20, 3 August 2016 (UTC)

@Coffee: I'll apologise up front. Yes, I am refusing to engage with Arianewiki1. If I get in trouble for that, then so be it. After repeated previous attempts to resolve differences about content impersonally and calmly, I can no longer assume good faith. Arianewiki1 has accused me of just about every Wikicrime there can be simply for disagreeing, been abusive, threatening, conniving, and for a while stalked my edits past and present looking for things to get angry about. I have reached the conclusion that there can be no useful engagement with Arianewiki1 - I see no real desire for constructive discussion, only dominance games and attempts to trip up other editors with violations of some rule or other. To protect my own sanity, I try to stay out of the way and no longer respond to any rants, barbs, or threats from Arianewiki1. Again, I'm sorry for not finding a way to handle this better.

In your preferences (click at the top of the page), on the gadgets tab you can find HotCat. Once you have saved this, any page you go to will have some buttons in the categories that make it quick and easy to edit them. There is also autocomplete so you always get good categories. Just above the HotCat checkbox is "Citation Expander". This will add a button to the editing window toolbar that you can click to make Citation Bot run on the current page. Then you can just create a cite journal template with a bibcode or doi in it, Citation Bot will do the rest. Lithopsian (talk) 18:42, 31 July 2016 (UTC)

You seem to be following me! :)

Hi! I've noticed that after making edits to articles as part of my current project relating to the IAU WGSN, you frequently shortly thereafter make edits of your own. Not that I have any objections to your edits, but I was wondering how you were seemingly following me? Do you simply have all these articles on your watchlist or have you some clever method of keeping track that I might find useful sometime in the future? Cuddlyopedia (talk) 09:25, 17 August 2016 (UTC)

@Cuddlyopedia: It is possible to examine the edit list of a user (contributions page), but I don't have any fancier methods than that. Recent edits will show up very easily in a nice popup by hovering over a user link in the watchlist if you have that enabled from your preferences, good for checking where else vandals might have been. But in your case it is just that you're editing articles on my watchlist. I don't have every astronomy article on my watchlist, but I do have several thousand, mostly individual stars. Whenever an edit shows up I take a quick look at the edit, then very often give the article itself a scan to see if anything strikes me as needing work. Many of them do need work! Lithopsian (talk) 10:27, 17 August 2016 (UTC)

OK. Thanks for the two tips. The 1st is straightforward enough, but I can't find where to enable the 2nd in my preferences? And you're right about the star articles! Cuddlyopedia (talk) 08:22, 18 August 2016 (UTC)

@Cuddlyopedia: I think the preference is Navigation Popups on the Gadgets tabs. I find it incredibly useful. Lithopsian (talk) 16:38, 18 August 2016 (UTC)

I recommend not using either of those. Stars don't sit plonk on the main sequence at the same spot over their main sequence lifetime..and many are unusual. And many have interstellar extinction between them and us. Best to use secondary sources if possible (i.e. the journal articles in the reference.).

List of brightest stars : Continuing problems

I tried to compromise with your request of adding sources, but you continue to not even to both to do so on the Talk page. Being an individual who has done and measured stars via photometry using comparison stars, it is clear to me your last edits only cherry-picked old sources by selecting material to suit your own arguments - and ignored mine. You've continue to point-blank refused to engage in solving these issues, and refuse to understand my point of view no show no willingness to compromise.

Fake star name pointing to star article

You seem experienced, so I ask you. I have found this misleading redirect page [19] where the reported fake name Urodelus is pointing to Epsilon Ursae Minoris. Do you know what is the best way to remove this redirect without going through the process of nominating it for deletion? Eynar Oxartum (talk) 10:56, 11 October 2016 (UTC)

I'm not really an expert on Wikipedia policies and procedures. Redirects are not especially easy to delete, partly because there is generally very little cost and confusion by even a poor or unlikely redirect title. You might try for a speedy delete but I'm not sure if it will go through as an "implausible typo or misnomer". Other than that it needs the full discussion, although there isn't likely to be much discussion for something this obscure. I'll watch and pipe up if you request a delete.

Hi L,

You left a comment on a page that I created stating that it requires better references. The information on the page is as I have received it from the professor himself. I might have changed a bit of English. But most of it is the way the professor or the scientist sent it to me.

Where do I find references to personal comments of these professors and scientists?

Annakoppad (talk)Annakoppad —Preceding undated comment added 06:26, 11 November 2016 (UTC)

Yes, that can be difficult but Wikipedia is an encyclopaedia, not a newspaper. You may know something, but for Wikipedia it needs to be verifiable. This is especially important in biographies of living people, for obvious reasons. I've only tagged the information that is uncited since it does not appear to be particularly contentious, but another editor would be quite justified in simply removing it all, so there is some incentive to finding published sources. Full policy guidelines are here. When I get time, I will come back to the astrophysics part - that's more my field and it does need to be changed. Lithopsian (talk) 22:31, 11 November 2016 (UTC)

User group: New Page Reviewr

Hello Lithopsian.

Based on the patrols you made of new pages during a qualifying period in 2016, your account has been added to the "New page reviewers" user group, allowing you to review new pages and mark them as patrolled, tag them for maintenance issues, or in some cases, tag them for deletion. The list of articles awaiting review is located at the New Pages Feed.

New page reviewing is a vital function for policing the quality of the encylopedia, if you have not already done so, you must read the new tutorial at New Pages Review, the linked guides and essays, and fully understand the various deletion criteria. If you need more help or wish to discuss the process, please join or start a thread at page reviewer talk.

• Be nice to new users - they are often not aware of doing anything wrong.
• You will frequently be asked by users to explain why their page is being deleted - be formal and polite in your approach to them too, even if they are not.
• Don't review a page if you are not sure what to do. Just leave it for another reviewer.
• Remember that quality is quintessential to good patrolling. Take your time to patrol each article, there is no rush. Use the message feature and offer basic advice.

The reviewer right does not change your status or how you can edit articles. If you no longer want this user right, you may ask any administrator to remove it for you at any time. In case of abuse or persistent inaccuracy of reviewing, the right can be revoked at any time by an administrator. MediaWiki message delivery (talk) 01:34, 19 November 2016 (UTC)

Roffey Park Institute

Hello there. I've haven't logged into Wikipedia for a few days which is why I missed the speedy deletion of Roffey Park Institute. I create the article because I do believe that it is a notable UK management research institution that has been around from the 1940s (I think). I was hoping that others (or indeed myself) night be able to contribute to it. Now the page has been deleted, I can't quite remember what the article looked. Can it be reinstated? Thanks Seaweed (talk) 15:16, 17 December 2016 (UTC)

You can ask the deleting admin (not me, the one that actually did the delete) to restore the page to your userspace so you can work on it some more. They will usually do this, although it's no guarantee the article will be acceptable in the future. Only in very unusual circumstances would they restore it directly to article space in the hope of someone doing some more work. Be careful about attempting to replace it since replacement of a deleted article with something essentially the same is frowned-upon. This would be a good time to read the WP:NOTABILITY guidelines since you will ultimately have to meet those or the article will get deleted again, speedily or otherwise. An article will only be speedily deleted if it makes no credible claim of significance, but may still be deleted after discussion if it makes claims and still turns out not to be notable. A notable organisation might still be speedily deleted if you neglected to mention the reasons why it is so famous. I also seem to remember the article might have been overly promotional? Maybe not, but watch out for that (and copyright) especially when you're sourcing material from the company itself. Lithopsian (talk) 20:55, 17 December 2016 (UTC)

Thanks for that information. I'm managed to find a cached version of the page and I now remember it was just a single sentence and small company information. I don't think anyone else had edited the page, so perhaps Roffey Park Institute is not as notable as I thought it was. I'm not connected to them in any way, so it wasn't promotional. I'll leave it as deleted. Seaweed (talk) 17:09, 18 December 2016 (UTC)

It is gone. I'm sure that everything you say is true, real product, real company, real sales, trademark, patents, and all the rest, but that's not what counts. Might be time to read up on notability. Articles which don't meet the notability criteria will be deleted. If they don't even attempt to establish notability, or if they cross other lines such as copyrighted text or excessively promotional tone, then they will be speedily deleted. Remember that Wikipedia is here to provide information on subjects that a significant number of people globally might be tempted to search, not to advertise every company trying to get noticed. You may also wish to read the policies on paid editing and conflict of interest. It is not prohibited to write about subjects that you have a close connection to, or even that you have been paid for, but it is important to be fully open to avoid any accusations of bias.

UDF objects

I understand why VY Orionis or articles about stars with no significant sources would be AfDed, but although the Hubble Ultra-Deep Field (UDF) object-related articles do not have lots of sources, they are somewhat important. I create UDF object articles because it would be helpful for Wikipedia to have lots of articles about galaxies that are almost as old as the Universe. SpaceDude777 (talk) - December 22, 2016 - 7:33 UTC

Not entirely up to me. We're about to find out what others think, fingers crossed. I'll give my opinion though :) First, WP:NASTRO is quite clear. Not naked eye, no significant coverage, not in Wikipedia. The reason is obvious enough: there are billions of astronomical objects and all except a few thousand are simply uninteresting to anyone that would want to use Wikipedia as a source. Specific to the UDF catalogue, do you plan on creating 10,000+ articles about them? Probably not (hopefully not!), so you are cherry-picking "interesting" ones. I and one or two other people have been approving some of them that make some sort of claim to notability even if they don't quite meet WP:NASTRO (eg. closest UDF object), but creating a one-line stub just because you identified a blob on an image doesn't really cut it IMO. If even you can't find anything to say about it, probably there isn't anything to say about it. If you think the UDF is important, perhaps a better place to focus your enthusiasm would be Hubble Ultra-Deep Field. It is currently rated as start-class, but could easily become C-class. For UDF objects which don't rate their own article, they can always be an entry in a list or an image in a gallery. Lithopsian (talk) 19:57, 22 December 2016 (UTC)

Pan-STARRS Sky Survey Images now available

I just thought I'd let you know that recently, Pan-STARRS 1 released one of the largest sky surveys yet, and images of astronomical objects can be accessed at http://ps1images.stsci.edu/cgi-bin/ps1cutouts (you just type an object's name in the box), and read that Pan-STARRS 1 data and images can be used for publications and commercial use as long as they are acknowledged (http://ipp.ifa.hawaii.edu/). So, for articles for astronomical objects that don't have images, we can use Pan-STARRS 1 images. If I'm wrong, please notify me. SpaceDude777 (talk) December 30, 2016: 2:57 UTC.

Open Supernova Catalog

Howdy, as you seem to be a fairly prolific editor of astronomy-related Wikipedia articles, I thought I'd let you know about the Open Supernova Catalog (https://sne.space), which has collected a vast amount of data on individual supernovae, including near-complete collections of light curves, spectra, and metadata.

I'm the current manager of the OSC, and I'd like to copy a lot of the content from the OSC onto Wikipedia (such as plots of light curves, pictures of host galaxies, etc.), but I wasn't sure how to get started, as I'm definitely a novice Wikipedia editor! Do you have any recommendations on how to best get this done? Is there a working group that keeps the supernova-related pages up to date?

Thanks! — Preceding unsigned comment added by Quaoar (talk • contribs) 17:15, 16 January 2017 (UTC)

There is no specific group that I'm aware of for just Supernova articles. You could start at WikiProject Astronomy and the subgroup for astronomical objects (not covered by other groups).

Were you thinking of creating new articles? On specific supernovae? It would probably be frowned upon to go madly in that direction. Read WP:NASTRO for guidelines on which objects would be considered notable for Wikipedia purposes, probably not a great many supernovae. Mass creation of articles from external data should be discussed first at the relevant project pages. On the other hand, there are already quite a few articles and for the most part not of great quality or depth. The core Supernova and confusingly overlapping Type Ia supernova, Type II supernova, and Type Ib and Ic supernovae articles are generally fairly complete, but there is always room for improvement. There is always the possibility of lists, which can be made up of many objects which would not be notable in themselves.

At the end of the day there is little point creating articles about non-notable subjects because they are likely to be deleted, although personally I tend to be quite tolerant of borderline objects where the article is well-written, well-sourced, and complete. Write a pointless stub about anything except the most famous of objects and it'll be gone before you can blink :) I'm not sure what the source of the OSC data is, whether it is a primary or secondary source, or portal similar to Simbad. It may make a useful reference in supernova articles, or general link.

The last thing is the issue of copyright. Material for Wikipedia cannot, except for minor quotations and occasional fair use exceptions, be copyrighted. Almost all material is copyrighted explicitly or by default, but can be released under a suitable license (Creative Commons) or released into the public domain. Images are generally held at Wikimedia Commons for use across all Wikipedia sites. Images which are non-free but considered appropriate for use on Wikipedia (don't ask, its a legal minefield!) can occasionally be uploaded directly on wikipedia.org.

Thanks Lithopsian! I was more thinking about fleshing out the few dozen stubs/starts for supernovae on your user page: [[20]]. The data on the OSC is secondary, gathered from a wide variety of sources, which are listed in full on the individual OSC pages. The simplest thing to do might just be to provide links to the relevant OSC pages, but it's also a good place to farm data about various supernovae for the infoboxes. Not every supernovae should get a page of course, just the notable ones.

I'm not intending to do much of this myself, but I figured it was working making the astronomy aficionados on Wikipedia aware of the page's existence and potential utility. --Quaoar (talk) 11:29, 17 January 2017 (UTC)

Autopatrol

Hi Lithopsian, I just wanted to let you know that I have added the "autopatrolled" permission to your account, as you have created numerous, valid articles. This feature will have no effect on your editing, and is simply intended to reduce the workload on new page patrollers. For more information on the patroller right, see Wikipedia:Autopatrolled. Feel free to leave me a message if you have any questions. Happy editing! Fabrictramp | talk to me 00:30, 5 February 2017 (UTC)

Speedy deletion nomination of M Puppis

A tag has been placed on M Puppis requesting that it be speedily deleted from Wikipedia. This has been done under section G6 of the criteria for speedy deletion, because it is an orphaned disambiguation page which either

• disambiguates two or fewer extant Wikipedia pages and whose title ends in "(disambiguation)" (i.e., there is a primary topic); or
• disambiguates no (zero) extant Wikipedia pages, regardless of its title.

Under the criteria for speedy deletion, such pages may be deleted at any time. Please see the disambiguation page guidelines for more information.

If you think this page should not be deleted for this reason, you may contest the nomination by visiting the page and clicking the button labelled "Contest this speedy deletion". This will give you the opportunity to explain why you believe the page should not be deleted. However, be aware that once a page is tagged for speedy deletion, it may be removed without delay. Please do not remove the speedy deletion tag from the page yourself, but do not hesitate to add information in line with Wikipedia's policies and guidelines.

Upsilon^2 Ceti

The Bayer designation υ² for Flamsteed's 56 Ceti was evidently introduced by Flamsteed himself (as reported in Wagman's Lost Stars). [Correction: 56 was υ¹, 59 was υ².] Lalande's version of Flamsteed's catalog includes it (available on Google Books, see link at 56 Ceti). Our article for 56 Ceti says Bode carried it forward, but I don't have Bode to hand, so can't check. -- Elphion (talk) 22:52, 14 February 2017 (UTC)

With a reference, you could put it back. I couldn't find anything about υ², or υ¹ for that matter. Didn't look in the obvious place for weird designations of course. What prompted me to make the changes was that υ¹ was renamed, by someone else, to simply υ Ceti. I don't know if it all merits going back to the superscripts, or just a quick note in the articles since it is hardly common usage. Lithopsian (talk) 16:15, 15 February 2017 (UTC)

Just to clarify, in case you don't watch the relevant obscure pages: I replaced the υ² and υ¹ designations with just υ at Table of stars with Bayer designations and Table of stars with Flamsteed designations. Lithopsian (talk) 16:26, 15 February 2017 (UTC)

Yes, the changes in the list articles told me you were up to something :-). Historically, Bayer had just the one upsilon, and Flamsteed added the second. The 19th century consolidators (Argelander and Baily) felt that upsilon^2 was a bridge too far, and reverted to Bayer's designation, and the superscript versions appear to have dropped out of use. There's a note of the older usage at 56 Ceti, and I'm thinking of adding one to Upsilon Ceti. We don't use the older notation at List of stars in Cetus, and presumably don't need to at the two articles you edited -- unless the goal of those lists is to list *every* "Bayer" designation. -- Elphion (talk) 17:59, 15 February 2017 (UTC)

I've been thinking about what each page should contain, given that we have a reference for the terms υ² and υ¹, however uncommon they may be in actual use. The List of stars in Cetus probably shouldn't show them, and doesn't, given that they are largely of historical interest. The Table of stars with Flamsteed designations certainly shouldn't show it. It should show the designation by which the star is commonly known. The Table of stars with Bayer designations maybe should show it, but might need a note explaining the alternate and more common usage - not 100% sure on that though. My thinking is that it is an attempt to be a thorough cross-reference for Bayer designations, even the ones that are a bit obscure. Lithopsian (talk) 16:11, 16 February 2017 (UTC)

That works for me. I've added a note (and the Flamsteed number 59) to Upsilon Ceti -- and corrected the note at 56 Ceti (56 was upsilon^1, 59 was upsilon^2). -- Elphion (talk) 20:47, 16 February 2017 (UTC)

Deletion of Fareportal

I've posted here about the speedy deletion of Fareportal - https://en.wikipedia.org/wiki/Talk:Fareportal#This_page_should_not_be_speedy_deleted_because...

Fareportal seems to me to meet the notability guidelines for Wikipedia - its a pretty big company. It may not have done a lot of notable stuff in and of itself, but I think the article I posted reflects that, in just covering the key details. Draykyle (talk) 20:17, 23 February 2017 (UTC)

Eta Carinae for TFA

Hi Lithopsian. This is just a friendly note to let you know that the Eta Carinae article, which you nominated at FAC, has been scheduled as today's featured article for March 12, 2017. If you're interested in editing the main page text, you're welcome to do so at Wikipedia:Today's featured article/March 12, 2017. Thanks! — Chris Woodrich (talk) 02:57, 23 February 2017 (UTC)

Precious

"look at all the stubs ..."

Thank you for quality articles such as stars and stellar systems, such as Eta Carinae, improved in collaboration, for project work (talk page tags, moves and redirects), for rewriting the Copernican principle, for your modest user page of the astronomy statistics, - stellar: you are an awesome Wikipedian!

Chinese whisper?

I noticed you removed a reference in this edit, saying it was a Chinese whisper. Can you explain what you meant by that? While I dislike Phys.org and would have cited the paper itself had I noticed it, the paper itself has been published by MNRAS. — Huntster (t @ c) 14:29, 14 March 2017 (UTC)

Chinese whisper, a copy potentially subtly reworded compared to the original. The original journal paper is also cited so little point having a second-hand copy unless there is some doubt about notability. Lithopsian (talk) 14:32, 14 March 2017 (UTC)

Declined speedy deletion nomination of Raise Data Recovery

Hello Lithopsian. Speedy deletion work is important and I do appreciate the effort. I would just ask that you please review the criteria carefully because accuracy is also important. On that issue, I have declined your speedy deletion nomination of Raise Data Recovery as an article that does not credibly indicate the importance or significance of the topic under CSD A7. That criterion did not apply because the article was about a computer program, and A7 only applies to articles on real persons or groups, individual animals, organisations, web content and organised events. Adam9007 (talk) 22:39, 16 March 2017 (UTC)

Will do. I got it in my head it was a company ... but no. Lithopsian (talk) 22:42, 16 March 2017 (UTC)

Ok I got one....

Right, I have buffed Capella on and off over the years. It was improved to GA status by Spacepotato. I like the history stuff and am good at prose, but am not so crash hot at the astrophysics. And astro articles are much harder than biology articles to get through FAC. Feel free to give it a good going over, fine-tune the info and would be cool to do a co-nomination (or even three way nom if Spacepotato is still interested in it. Cheers, Cas Liber (talk · contribs) 21:11, 23 February 2017 (UTC)

Not sure Spacepotato is around at the moment, but I went over the article and made some changes and updates. I'll go over it in a day or two and see if anything big strikes me on the science side. Otherwise it probably needs quite a lot of copyedit. Lithopsian (talk) 22:45, 16 March 2017 (UTC)

Kepler-351b

I just wanted you to know that I nominated Kepler-351b for deletion. Can you make sure that the nomination was a good idea? SpaceDude777 (talk) —Preceding undated comment added 19:20, 19 March 2017 (UTC)

You're preaching to the choir here :) I'll tag along with the RfD and see how it goes. Lithopsian (talk) 20:09, 19 March 2017 (UTC)

Capella redux..and Rigel

Ok, have nominated Capella at Wikipedia:Featured article candidates/Capella/archive1. So keep an eye and we'll see what crops up. Given you like luminous stars...Rigel might be a good one to buff too. FA-hood serves two purposes - (1) closest thing we have to a Stable Version, FAC completion is a good reference point in case an article degrades. (2) getting something on the main page. Always fun. Cas Liber (talk · contribs) 10:36, 19 March 2017 (UTC)

Another one might be Epsilon Aurigae, which the evidence is firming for some sort of dust cloud/disk thing, possibly around a B-type secondary star..? Or Canopus..just getting all the evidence together..? Cas Liber (talk · contribs) 23:32, 23 March 2017 (UTC)

equinox terms

In the southern hemisphere do they really call the equinox in March "vernal" or "spring" and the one in September "autumnal" or "fall" in spite of the actual seasons? Also, what leads you to believe the Latin names are more common and less ambiguous than the English ones? --Lasunncty (talk) 05:43, 3 April 2017 (UTC)

Take it to the article talk page where it can be fully discussed and hopefully some form of consensus reached. Lithopsian (talk) 12:59, 3 April 2017 (UTC)

Deletion of Golden Proportions Page

Hi there,

Thank you for your message. I was teaching a group of dental students to edit as part of the Wikipedia Collaboration of Dental Schools. I completely understand that when a page is created it is not meant to be left blank. The students were meant to add the content straight away but there has been a delay. I created the page to make it easier for them to get started. I will have them re-create themselves when they are ready to add the content. Thanks!
