Abstract
The bulge remains a mysterious part of the galaxy, due to significant foreground reddening, necessitating observations in the infrared. Though APOGEE-2 and other observing programs are observing bulge field stars, there are old, relatively metal-poor bulge globular clusters that remain unstudied. These clusters offer the chance to study the earliest assembly history of the bulge. This proposal requests IGRINS time to observe stars in four of these moderately metal-poor bulge globular clusters. The high-precision abundances from these spectra will probe the nature of star formation and/or accretion in the early bulge.
