High-resolution spectroscopic survey of 671 GK giants. I. Stellar atmosphere parameters and abundances

摘要: 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. table polynomial coefficients 10 color-T(eff) relations presented. Stellar atmosphere parameters, including log g, Fe/H, microturbulent velocity, are computed each star, using spectra various published photometric catalogs. For elemental abundances a variety species LTE spectrum synthesis program adopted parameters. 62 refs.
