Researchers claim to have found the oldest stellar disk in the Milky Way galaxy

A team of astronomers and astrophysicists at the Chinese Academy of Sciences and the University of Toronto has found what they believe is the oldest stellar disk in the Milky Way galaxy. In their study, reported in the journal Nature Astronomy, the group used high-α stars with substantial orbital angular momentum to conduct age determinations across a wide range of stars in the galaxy. A team of astronomers and astrophysicists at the Chinese Academy of Sciences and the University of Toronto has found what they believe is the oldest stellar disk in the Milky Way galaxy.
