ABUNDANCES OF HELIUM AND OTHER ELEMENTS IN ATMOSPHERES OF CLASSICAL CEPHEIDS
The chemical composition of three classical cepheids δ Cep, η Aql and ζ Gem, has been investigated by using model atmospheres' method. It is shown that Na and Mg are overabundant (≈+0.35 dex), C and 0 are slightly underabundant (≈ -0.20 dex) relative to the Sun. The atmospheric abundances for o...
