Abundances of stars in different Galactic subsystems
arXiv:1312.4592
Abstract
This is a brief overview of the elemental abundance patterns that have been observed in the different Galactic stellar populations. Main focus is on studies that are based on high-resolution spectra of dwarf and subgiant stars, and in some cases red giant stars. Of particular interest is the thin-thick disk dichotomy, the variation of abundances and stellar ages with galactocentric radius, multiple stellar populations in the Galactic bulge region, and how some of these may be connected with other Galactic populations.
