Population 1 vs population 2 stars
WebAbout 1/3 of the local disk is in gas and about 2/3 is in stars. About 1 star in 500 near the Sun comes from the stellar halo (spheroid), the rest coming from the disk. About 5-10 … Population I, or metal-rich, stars are young stars with the highest metallicity out of all three populations and are more commonly found in the spiral arms of the Milky Way galaxy. The Sun is an example of a metal-rich star and is considered as an intermediate population I star, while the solar-like Mu Arae is much richer in metals.

WebThe best evidence for a distinct population of stars would be a lower cutoff in the metallicity distribution of Population II stars. If the first stars had the same IMF as today, with a lower cutoff at about 0.1 M , one might expect stars smaller than 0.8 M (whose lifetime exceeds the age of the Universe) to display arbitrarily low metallicity.
