This means that SDSS J0018−0939 most likely preserved the elemental abundance ratios produced by a first-generation very-massive star. [7] First generation stars are expected to self-regulate their growth by radiative feedback in the formation process, and to achieve masses typically tens of times that of the Sun. A fraction of stars might ...
HE 1327-2326, discovered in 2005 by Anna Frebel and collaborators, [2] was the star with the lowest known iron abundance until SMSS J031300.36−670839.3 was discovered. [5] The star is a member of Population II stars , with a solar-standardised iron to hydrogen index [Fe/H], or metallicity , of −5.4±0.2.

HE 1523-0901 is the designation given to a red giant star in the Milky Way galaxy approximately 9,900 light-years from Earth. It is thought to be a second generation, Population II, or metal-poor, star ([Fe/H] = −2.95). The star was found in the sample of bright metal-poor halo stars from the Hamburg/ESO Survey by Anna Frebel and
