Descripción
Galactic bulges contain dense, information-rich fossil records of star
formation and galaxy assembly, encoded in the chemo-dynamical patterns
of the stellar populations. The Milky Way's bulge is the only one in
which we can resolve the chemistry and kinematics of individual stars in
those populations, but we still do not fully understand the formation
and subsequent evolution of the bulge. The SDSS APOGEE survey affords
the opportunity to characterize in detail large numbers of stars
throughout the Milky Way's entire bulge. We present an analysis of the
chemo-dynamical patterns observed in the full set of ~15,000 inner
Galaxy stars from APOGEE-1, and compare these patterns to extragalactic
bulges and to evolutionary models that include both chemistry and
kinematics for the stellar populations. We discuss implications for
disentangling contributions from different bulge formation scenarios.
