Spectroscopic analysis of the bulge Globular Cluster ESO~456-SC38
  It has been suggested that the oldest stellar populations in the Milky Way
Galaxy are tightly bound and confined to the central regions of the Galaxy.
This is one of the reasons why a handful of globular clusters located in the
bulge region are thought to be remnants of the primeval formation stages of the
Milky Way. The globular cluster, ESO 456-SC38 (Djorgovski~2) is one such
cluster; it has a blue horizontal branch, is projected very close to the center
of the Galaxy, and has an orbit confining it to the bulge/bar region. The first
alpha abundances of seven stars in this heavily reddened cluster are presented
using APOGEE DR16. A significant spread in the abundances of N, C, Na, and Al
indicates the presence of multiple stellar populations in this cluster. Using
Gaia DR2 proper motions and radial velocities from BRAVA-RR, we confirm RR
Lyrae stars belong to this globular cluster.
