Giants: Chemical Composition

Scientific paper

The physical parameters and chemical composition of the atmospheres of three stars with CN2-indices are derived using high dispersion coudé echelle CCD-spectra obtained at the 1-m telescope of the Special Astrophysical Observatory of the Russian Academy of Sciences. The stars with strong CN-indices are found to be typical giants of the galactic thin disk with the overabundance of Na and the solar composition of neutron capture elements. The star HD 188056 (suspected as SMR) has [Fe/H] = 0.14 and the overabundance of C, Al and Mn.
