Metallicity Gradients in the Milky Way Disk as Observed by the SEGUE Survey
Judy Y. Cheng, Constance M. Rockosi, Heather L. Morrison +6
The observed radial and vertical metallicity distribution of old stars in the Milky Way disk provides a powerful constraint on the chemical enrichment and dynamical history of the…
Investigation of the errors in SDSS proper-motion measurements using samples of quasars
Ruobing Dong, James Gunn, Gillian Knapp +2
We investigate in detail the probability distribution function (pdf) of the proper-motion measurement errors in the SDSS+USNO-B proper-motion catalog of \citet{mun04} using clean q…
Structure and Population of the NGC55 Stellar Halo from a Subaru/Suprime-Cam Survey
Mikito Tanaka, Masashi Chiba, Yutaka Komiyama +2
As part of our survey of galactic stellar halos, we investigate the structure and stellar populations of the northern outer part of the stellar halo in NGC55, a member galaxy of th…
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…
Globular Cluster Abundances from High-Resolution, Integrated-Light Spectroscopy. III. The Large Magellanic Cloud: Fe and Ages
J. E. Colucci, R. A. Bernstein, S. A. Cameron +1
In this paper we refine our method for the abundance analysis of high resolution spectroscopy of the integrated light of unresolved globular clusters (GCs). This method was previou…
Insight Into the Formation of the Milky Way Through Cold Halo Substructure. II. The Elemental Abundances of ECHOS
Kevin C. Schlaufman, Constance M. Rockosi, Young Sun Lee +2
We determine the average metallicities of the elements of cold halo substructure (ECHOS) that we previously identified in the inner halo of the Milky Way within 17.5 kpc of the Sun…
Formation and Evolution of the Disk System of the Milky Way: [alpha/Fe] Ratios and Kinematics of the SEGUE G-Dwarf Sample
Young Sun Lee, Timothy C. Beers, Deokkeun An +10
We employ measurements of the [alpha/Fe] ratio derived from low-resolution (R~2000) spectra of 17,277 G-type dwarfs from the SEGUE survey to separate them into likely thin- and thi…
