Abstract (from CDS):
We present elemental abundances found for the peculiar galactic Cepheid V473 Lyr.
Result. were obtained for 38 species of 32 chemical elements. We confirmed previous conclusion that this s-Cepheid is slightly underabundant in metals ([Fe/H]=-0.16). Carbon follows the usual rule to be deficient in the Cepheid atmospheres. No significant overabundance was detected for sodium. Other elements with determined abundances do not show any marked anomalies. Atmospheric parameters of V473 Lyr derived in the present study are the following: Teff=6100K, logg=2.2, Vmicro=3.8km/s, Vmacro=4.5km/s.
