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 ...
In reality, many population I stars are also found mixed in with the older population II stars. In 1944 , Walter Baade categorized groups of stars within the Milky Way into stellar populations . In the abstract of the article by Baade, he recognizes that Jan Oort originally conceived this type of classification in 1926 .
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).

It had been thought that NGC 2808, like typical globular clusters, contains only one generation of stars formed simultaneously from the same material. In 2007, a team of astronomers led by Giampaolo Piotto of the University of Padua in Italy investigated Hubble Space Telescope images of NGC 2808 taken in 2005 and 2006 with Hubble's Advanced Camera for Surveys.
