Abstract:
The results of a spectroscopic analysis of 15 stars that are
photometric analogues of the Sun are reported. The effective
temperatures and surface gravities in the stellar atmospheres are
derived from published photometric indices and the HIPPARCOS
parallaxes. The abundances of 33 elements ranging from lithium to
europium are analyzed based on high-dispersion spectra taken with the
new Coude echelle spectrometer of the Terskol Observatory in the
northern Caucasus. The main parameters of most of the stars agree with
the data of an [Fe/H] catalog published in 2001. Our study of the
chemical compositions of the sample stars indicates that photometric
analogues of the Sun can be divided into three groups according to
their elemental abundances: six stars have solar chemical composition,
four have abundance excesses, and five have some abundance
deficiencies. The sample contains two metal-deficient subgiants
(HD 133002 and HD 225239).
