The [Fe/H], [C/Fe], and [alpha/Fe] distributions of the Bootes I Dwarf Spheroidal Galaxy
David K. Lai, Young Sun Lee, Michael Bolte +5
We present the results of a low-resolution spectral abundance study of 25 stars in the Bootes I dwarf spheroidal (dSph) galaxy. The data were obtained with the LRIS instrument at K…
Chemical Abundances for Evolved Stars in M5: Lithium through Thorium
David K. Lai, Graeme H. Smith, Michael Bolte +4
We present analysis of high-resolution spectra of a sample of stars in the globular cluster M5 (NGC 5904). The sample includes stars from the red giant branch (seven stars), the re…
The SEGUE Stellar Parameter Pipeline. V. Estimation of Alpha-Element Abundance Ratios From Low-Resolution SDSS/SEGUE Stellar Spectra
Young Sun Lee, Timothy C. Beers, Carlos Allende Prieto +7
We present a method for the determination of [alpha/Fe] ratios from low-resolution (R = 2000) SDSS/SEGUE stellar spectra. By means of a star-by-star comparison with degraded spectr…
A Unique Star in the Outer Halo of the Milky Way
David K. Lai, Constance M. Rockosi, Michael Bolte +5
As part of a program to measure abundance ratios in stars beyond 15 kpc from the Galactic center, we have discovered a metal-poor star in the outer halo with a unique chemical sign…
SDSS J142625.71+575218.3: The First Pulsating White Dwarf with a Large Detectable Magnetic Field
P. Dufour, G. Fontaine, J. Liebert +2
We report the discovery of a strong magnetic field in the unique pulsating carbon-atmosphere white dwarf SDSS J142625.71+575218.3. From spectra gathered at the MMT and Keck telesco…
Detailed Abundances for 28 Metal-poor Stars: Stellar Relics in the Milky Way
David K. Lai, Michael Bolte, Jennifer A. Johnson +3
We present the results of an abundance analysis for a sample of stars with [Fe/H]. The data were obtained with the HIRES spectrograph at Keck Observatory. The set include…
