High-Resolution Spectroscopic Survey of 671 GK Giants. I. Stellar Atmosphere Parameters and Abundances
Abstract
A high-resolution spectroscopic survey of 671 G and K field giants is described. Broad-band Johnson colors have been calibrated against recent, accurate effective temperature, T(eff), measurements for stars in the range 3900-6000 K. A table of polynomial coefficients for 10 color-T(eff) relations is presented. Stellar atmosphere parameters, including T(eff), log g, Fe/H, and microturbulent velocity, are computed for each star, using the high-resolution spectra and various published photometric catalogs. For each star, elemental abundances for a variety of species have been computed using a LTE spectrum synthesis program and the adopted atmosphere parameters.
