Antlia edit
This article is about a constellation with a few interesting tidbits. Buffed it up so I think it is the equal to the other 25 or so Featured constellation articles. Got a thorough going-over at GAN. All input appreciated. Cas Liber (talk · contribs) 04:39, 15 May 2016 (UTC)[reply]
NB: A wikicup nomination. Cheers, Cas Liber (talk · contribs) 10:07, 15 May 2016 (UTC)[reply]
Support: My concerns were addresses, so I'm giving my support for promotion to FA. Thank you. Praemonitus (talk) 22:50, 23 May 2016 (UTC)[reply]
Comment:The article is a bit short, but it's difficult to see how it could be further expanded. Overall it looks to be in good shape.Here are a few points that caught my eye during a read through:
"The system is classed as an A-type W Ursae Majoris variable": what is meant by A-type here? The term seems to be conflated with the variable type description. Only one of the pair is an A-class star.
"...unusual hot variable ageing star...", "...and is a unique variable...": how is it unusual or unique? This is not quite clear.
"...yellow-white F-type star but it has almost no hydrogen": the article says it is deficient in hydrogen; meaning only that it is lower than normal.
- As an R Coronae Borealis variable, it has a very low ratio of hydrogen. Might not be spelt out there but is elsewhere. Article itself talks of "striking" absence/weakness of H lines etc. Cas Liber (talk · contribs) 07:53, 21 May 2016 (UTC)[reply]
- Okay, yes. The 'R Coronae Borealis variable' article makes it clear that this star may have formed with negligible amounts of hydrogen. Praemonitus (talk) 22:50, 23 May 2016 (UTC)[reply]

"Peter Birren" and "Ian Ridpath": these names should be formatted in a manner consistent with the other referenced authors.

Comments. As always, feel free to revert my copyediting. - Dank (push to talk)
- "Its main stars have no particular pattern": I don't know what that means.
- It means a recognisable pattern like an Asterism (astronomy)....but I have removed the sentence as does not add much. I think its faintness more of a reason it didn't get recognised and second bit not true anyway Cas Liber (talk · contribs) 09:50, 21 May 2016 (UTC)[reply]
- " All but one were named in honour of instruments that symbolised the Age of Enlightenment. ... [he] chose names mostly from scientific instruments": Seems repetitive.
- Support on prose per my standard disclaimer. These are my edits.
Scanning quickly, it looks like you've addressed some but not all of Praemonitus's concerns.- Dank (push to talk) 16:55, 20 May 2016 (UTC)[reply]

Comments by Sarastro: A few nit-picks here, most of which concern making this a little more accessible for the general reader, which shouldn't be a problem in such a short article. Sarastro1 (talk) 18:44, 30 May 2016 (UTC)[reply]
- "a historical air pump": How is a historical air pump different from any other air pump? Can we be more precise what we mean by historical? Later on, we link to "air pump" but not here.
- "the constellation was introduced by Nicolas Louis de Lacaille": Introduced seems an odd word to use here, unless it is a technical term.
- "Abbreviated from Antlia Pneumatica, the constellation was introduced by Nicolas Louis de Lacaille in the 18th century": In fact, there's something a little uncomfortable with the use of "abbreviated" here. The constellation wasn't abbreviated, it's name was. So, could we combine these ideas and say that Lacaille named it and (as it says in the made body) Herschel invented the abbreviation? Or something less clumsy than my attempt there??
- "is counted among the 88 modern constellations": I know we link this, but as readers, we're left wondering what a modern constellation is, and how it differs from other constellations. Do we even need this in the lead?
- "The stars are so close they have a common envelope and will one day merge to form a single star.": I wonder, for the lead, do we need the part about the common envelope? It would make perfect sense if it read "The stars are so close they will eventually merge to form a single star", unless we can avoid repetition of "star".
- "lie within Antlia's borders": Not obvious to the general reader that a constellation may have a border
- "De Lacaille had observed and catalogued almost 10,000 southern stars during a two-year stay at the Cape of Good Hope, devising fourteen new constellations in uncharted regions of the Southern Celestial Hemisphere not visible from Europe": A few points here. I'm assuming this was his intention when he travelled to the Cape of Good Hope; but, did he do so of his own volition, did he do so on his own? Were other people doing similar things, or is this the random act of a madman? Did he base his constellations on anything, or was it just a case of "that looks a bit like an air pump"?
- The new constellations honoured scientific inventions of the Age of Enlightenment. They were criticised for not looking like what they were supposed to represent but then again almost no constellations look like what they are supposed to represent... Cas Liber (talk · contribs) 11:37, 31 May 2016 (UTC)[reply]
- "All but one were named in honour of instruments that symbolised the Age of Enlightenment": Did he name them, or did it come back to a committee? If the former, why not "He named all but one..."?
- "John Herschel proposed shrinking the name to one word, which was universally adopted": When?
- "Though Antlia was technically visible to Classical Greek astronomers, its stars were too faint to have been included in any ancient constellations.": What do we mean by "technically visible"? It's a bit jarring to read that it was visible but they couldn't see it! What about something like the portion of the sky in which it is located was visible, the stars of the constellation were too faint to be visible for inclusion in anything?
- Only brighter stars ended up forming the classical constellations - there were loads of fainter stars lying around that were not used. actually the more I look at it the more I realize the first segment is actually redundant....and have removed it Cas Liber (talk · contribs) 06:46, 1 June 2016 (UTC)[reply]
- "Lacaille depicted Antlia as a single-cylinder vacuum pump used in Papin's initial experiments, while Johann Bode chose the more advanced double-cylinder version.": This sentence is oddly placed here. Why not in the naming part?
- "while Johann Bode chose the more advanced double-cylinder version": In such a short article, can we not spare the reader a job and say who Bode was?
- "The International Astronomical Union later adopted it as one of the 88 modern constellations": When? Also, maybe a word about who the IAU are/were? And, again we might give a link, but I think we should explain here what the 88 modern constellations are.
- "There is no mythology attached to Antlia as Lacaille discontinued the tradition of giving names from mythology to constellations and instead chose names mostly from scientific instruments": Again, this sentence is a little oddly placed; this would be better in the naming paragraph. The way this sentence is written, it also looks like his contemporaries were still using mythology. True?
- "According to some, the most prominent stars that now comprise Antlia were once included within the ancient constellation Argo Navis, the Ship of the Argonauts, which due to its immense size was split into several smaller constellations by Lacaille in 1763.": According to who? And, by "within" I assume we mean within the borders of the constellation, but not actually part of the "picture" they formed. Otherwise we are contradicting the previous part which says that the stars were invisible in Classical times. Again, may be worth making the distinction for the general reader. And this is a bit more context for what Lacaille was up to: so did he take what was there and re-organise it? Or was he looking for new stars?
- "The three-letter abbreviation for the constellation, as adopted by the International Astronomical Union in 1922, is Ant.": IAU linked here but not earlier. And no date is given earlier. I wonder should this be combined with the earlier information about the IAU?
- "as set by Eugène Delporte in 1930": Again, a word or two of context would be good here.
- "Beta and Gamma Antliae (now HR 4339 and HD 90156) ended up in the neighbouring constellation Hydra once the constellation boundaries were delineated in 1930": This is the first we have seen of any such delineation. Surely worth mentioning earlier?
- In the part about the stars, I appreciate that we can't cater as much for the general reader (and I confess that my eyes glazed over a bit, so I might have missed something). However, I notice that "spectral type" is used a lot; I know nothing about this but notice that our article has sections on different letters, such as type K. Could we link each mention of spectral type to its letter in our article?
- "It is a loose face-on spiral galaxy of type Sc": What does loose mean in this sense? Sarastro1 (talk) 18:44, 30 May 2016 (UTC)[reply]
Support: I'm happy to support now. My only two remaining points are that I think it is worth saying more about the 88 constellations, as the obvious question is why were there modern constellations; the other one is that we now have the nicely informative "while German astronomer Johann Bode chose the more advanced double-cylinder version" but Bode appears from nowhere and it is not immediately obvious who he is, what he is doing and why he is doing it! However, these don't affect my support in any way. Sarastro1 (talk) 23:48, 1 June 2016 (UTC)[reply]
Support: I performed the good article review for this article a short time ago, where all of my concerns were addressed. I see that the article has been further improved since then. (As part of that review, I checked all sources to the best of my ability. In the end, I only had a couple of reservations about the technical prose, and I assume someone with a stronger astronomy background would help with that.)

- I've checked the GA source review/spotcheck and I think it suffices, thanks. Cas, I'm going to promote but could I suggest that the last two images might work better on the right, and also using "upright=1.n" (equivalent to 300px) for a proportional rather than fixed size?
