Spectroscopic age estimates for APOGEE red-giant stars: Precise spatial and kinematic trends with age in the Galactic disc
Over the last few years, many studies have found an empirical relationship between the
abundance of a star and its age. Here we estimate spectroscopic stellar ages for 178 825 …
