Descripción
Some studies of the Milky Way halo and all studies of the thick disk
populations suffer from difficulties cleanly separating out one galactic
component from another. This is largely due to magnitude limitations,
which produces a bias towards local solar neighborhood samples, where
the separation of the thick disk from the halo populations of the Milky
Way is problematic. Most studies have relied on metallicity or
kinematics to attempt to disentangle halo samples from thin and thick
disk samples. Using the new large data sets from the ESA Gaia mission,
the NASA Kepler mission, the SDSS/APOGEE survey and knowledge of stellar
interiors we explore the candidate halo and thick disk giants using
Galactic position, kinematics, mass, age, and chemistry. We explore the
correlations with chemical abundance ratios such as mass and [C/Fe] and
how these may inform future efforts to make clean samples of Milky Way
stellar components.
