Abstract

The algorithm of the determination of abundances in atmospheres of stars of spectral classes F, G, and K using fits to the observed spectral lines or selected parts of the blended lines is discussed. The technique allows to determine the parameters of the atmosphere, i.e., gravity, microturbulent velocity, rotational velocity of the star, and abundance of elements, for a given effective temperature of the star. At each stage of the iterative process the model atmosphere is recalculated for a new set of input data. The results of applying the procedure for the analysis of the spectra of the Sun (G2 V) and HD 101348 (G3 V) are discussed.
