Near-Infrared Spectroscopy of Carbon-Enhanced Metal-Poor Stars. I. A SOAR/OSIRIS Pilot Study
Timothy C. Beers, Thirupathi Sivarani, Brian Marstellar +3
We report on an abundance analysis for a pilot study of seven Carbon-Enhanced Metal-Poor (CEMP) stars, based on medium-resolution optical and near-infrared spectroscopy. The optica…
A Catalog of Candidate Field Horizontal-Branch and A-Type Stars. III. A 2MASS-Cleaned Version
Timothy C. Beers, Tiago Almeida, Silvia Rossi +2
We present coordinates and available photometric information (either from previous or recent broadband UBV observations, and near-infrared photometry from the 2MASS Point Source Ca…
Broadband UBVRI Photometry of Horizontal-Branch and Metal-Poor Candidates from the HK and Hamburg/ESO Surveys. I
Timothy C. Beers, Chris Flynn, Silvia Rossi +17
We report broadband UBV and/or BVRI CCD photometry for a total of 1857 stars in the thick-disk and halo populations of the Galaxy. The majority of our targets were selected as cand…
The Frequency of Carbon-Enhanced Metal-Poor Stars in the Galaxy from the HERES sample
Sara Lucatello, Timothy Beers, Norbert Christlieb +5
We estimate the frequency of Carbon-Enhanced Metal-Poor (CEMP) stars among very metal-poor stars, based on an analysis of 349 stars with available high-resolution spectra observed…
Bright Metal-Poor Stars from the Hamburg/ESO Survey. I. Selection and Follow-up Observations from 329 Fields
A. Frebel, N. Christlieb, J. E. Norris +9
We present a sample of 1777 bright (9<B<14) metal-poor candidates selected from the Hamburg/ESO Survey (HES). Despite saturation effects present in the red portion of the HES objec…
The Metallicity Distribution Function of the Halo of the Milky Way
Timothy C. Beers, Norbert Christlieb, John E. Norris +8
We report on the distribution of metallicities, [Fe/H], for very metal-poor stars in the halo of the Galaxy. Although the primary information on the nature of the Metallicity Distr…
