Abstract:
The atmospheric parameters and elemental abundances for ten thick-disk
red giants have been determined from high-resolution spectra by the
method of model stellar atmospheres. The results of a comparative
analysis of the [Na/Fe] abundances in the atmospheres of the
investigated stars and thindisk red giants are presented. Sodium in
the atmospheres of thick-disk red giants is shown to have no
overabundances typical of thin-disk red giants.
