The SEGUE Stellar Parameter Pipeline. II. Validation with Galactic Globular and Open Clusters
Y. S. Lee, T. C. Beers, T. Sivarani +13
We validate the performance and accuracy of the current SEGUE (Sloan Extension for Galactic Understanding and Exploration) Stellar Parameter Pipeline (SSPP), which determines stell…
Fluorine in a Carbon-Enhanced Metal-Poor Star
S. C. Schuler, K. Cunha, V. V. Smith +3
The fluorine abundance of the Carbon-Enhanced Metal-Poor (CEMP) star HE 1305+0132 has been derived by analysis of the molecular HF (1-0) R9 line at 2.3357 microns in a high-resolut…
Two Stellar Components in the Halo of the Milky Way
D. Carollo, T. C. Beers, Y. S. Lee +9
The halo of the Milky Way provides unique elemental abundance and kinematic information on the first objects to form in the Universe, which can be used to tightly constrain models…
Estimation of stellar atmospheric parameters from SDSS/SEGUE spectra
P. Re Fiorentin, C. A. L. Bailer-Jones, Y. S. Lee +5
We present techniques for the estimation of stellar atmospheric parameters (Teff,logg,[Fe/H]) for stars from the SDSS/SEGUE survey. The atmospheric parameters are derived from the…
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…
Elemental abundances of metal poor carbon rich lead star: CS29497-030
T. Sivarani, P. Bonifacio, P. Molaro +12
We present here the abundance analysis of a metal poor carbon rich lead star, CS29497-030. High resolution and high signal to noise spectra were obtained using the UVES spectrograp…
