Metallicity Gradients of Thick Disk Dwarf Stars
Kenneth Carrell, Yuqin Chen, Gang Zhao
We examine the metallicity distribution of the Galactic thick disk using F, G, and K dwarf stars selected from the Sloan Digital Sky Survey, Data Release 8. Using the large sample…
New Findings for the Blue Plume Stars in the Canis Major Over-Density
W. Lee Powell, Ronald Wilhelm, Kenneth Carrell +1
We obtained new UBV photometry and spectroscopy of Blue Plume (BP) stars in fields near the center of the Canis Major Over-Density (CMa). We combined analysis of the color-color di…
Identification of RR Lyrae Variables in SDSS from Single-Epoch Photometric and Spectroscopic Observations
Ronald Wilhelm, W. Lee Powell, Timothy C. Beers +9
We describe a new RR Lyrae identification technique based on out-of-phase single-epoch photometric and spectroscopic observations contained in SDSS Data Release 6 (DR-6). This tech…
