Chemical Abundances of the Leo II Dwarf Galaxy
Matthew Shetrone, Michael H. Siegel, David O. Cook +1
We use previously-published moderate-resolution spectra in combination with stellar atmosphere models to derive the first measured chemical abundance ratios in the Leo II dSph gala…
The Chemical Abundances of the Stellar Populations in the Leo I and Leo II dSph Galaxies
Tammy L. Bosler, Tammy A. Smecker-Hane, Peter B. Stetson
We have obtained spectra of 102 red giant branch (RGB) stars in the Leo I dwarf spheroidal galaxy (dSph) and 74 RGB stars in the Leo II dSph using LRIS on the Keck I 10-meter Teles…
The Effects of Age on Red Giant Metallicities Derived from the Near-Infrared Ca II Triplet
A. A. Cole, T. A. Smecker-Hane, E. Tolstoy +2
We have obtained spectra with resolution 2.5 Angstroms in the region 7500-9500 Angstroms for 116 red giants in 5 Galactic globular clusters and 6 old open clusters (5 with publishe…
The Ca II Triplet as an Abundance Indicator
T. Bosler, T. Smecker-Hane, A. McWilliam
How can we accurately determine the metallicity of faint red giant stars in nearby galaxies? The equivalent widths of the broad absorption lines from Ca II at 8498, 8542, and 8662…
