open cluster remnant age edit
Observations section states that "The typical age of these [open cluster] systems is about 150 Myr with a range of 50-200 Myr." That is a remarkably small age range.
At https://ui.adsabs.harvard.edu/abs/2014AAS...22344206H/abstract [Is Loden 1 an old and nearby star cluster? January 2014 Bibcode: 2014AAS...22344206H ] by
Eunkyu Han ; J L Curtis & J Wright, the abstract claims that cluster "Loden 1" seems to be about 2 Gyr old, and not simply tens or hundreds of millions of years old. ChgoJohn (talk) 01:19, 21 January 2022 (UTC)
adding: Wouldn't a remnant be much older than original fully-populated clusters? ChgoJohn (talk) 01:23, 21 January 2022 (UTC)
adding: i.e., from clusters themself aged 1-12gyr? ChgoJohn (talk) 01:25, 21 January 2022 (UTC)
