Abundance patterns in the Draco, Sextans, and Ursa Minor dwarf spheroidal galaxies.
SHETRONE M.D., COTE P. and SARGENT W.L.W.
Abstract (from CDS):
The first high-resolution abundance analysis for the distant Galactic globular cluster NGC 2419 is also presented. From a HIRES spectrum of a single red giant, we find a metallicity of [Fe/H]=-2.32±0.11 dex. This is slightly lower than, but still consistent with, published estimates based on low-resolution spectroscopy. With the possible exception of a slight enhancement in the abundances of some heavy elements such as Ce, Nd, Y, and Ba, the observed abundance pattern closely resembles those exhibited by red giants in M92: a nearby, well-studied globular cluster of nearly identical metallicity.
