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…
Dynamical evidence of the age--metallicity relation in the Milky Way disk
H. J. Rocha-Pinto, R. H. O. Rangel, G. F. Porto de Mello +2
We studied the relationship between the average stellar abundance of several elements and the orbital evolution of stars in the neighbourhood of the Sun, using both observational d…
Optical polarimetric monitoring of the type II-plateau SN 2005af
A. Pereyra, A. M. Magalhaes, C. V. Rodrigues +4
Aims. Core-collapse supernovae may show significant polarization that implies non-spherically symmetric explosions. We observed the type II-plateau SN 2005af using optical polarime…
