Detailed near-IR stellar abundances of red giants in the Inner Bulge and Galactic Center
(2017) In Proceedings of the International Astronomical Union 13(S334). p.82-85- Abstract
Owing to their extreme crowding and high and variable extinction, stars in the Galactic Bulge, within ±2° of the Galactic plane, and especially those in the Nuclear Star Cluster, have only rarely been targeted for an analyses of their detailed abundances. There is also some disagreement about the high end of the abundance scale for these stars. It is now possible to obtain high dispersion, high S/N spectra in the infrared K band (~2.0 - 2.4 m) for these giants; we report our progress at Keck and VLT in using these spectra to infer the composition of this stellar population.
