Study of photometric solar-analog stars from the spectra obtained with the 2-m telescope at the Terscol Observatory
Abstract
We obtained high-resolution spectra of a sample of solar analogs by using a coude-echelle-spectrometer of the 2-m telescope of the Terskol Observatory in 1999-2000. We derived fundamental parameters of the atmospheres (T_{eff}, lg{textsl g}) of these stars and determined abundances of 30 elements from carbon to europium using measured equivalent widths. Moreover, the abundance of lithium was calculated from the Li I 670.8 nm line profiles. We also analyzed kinematic characteristics of these stars based on measured radial velocities.
