THE INVESTIGATION OF CEPHEIDS RT AUR, T VUL, κ PAV BY A TWO-COMPONENT

Abstract

For 3 cepheids (RT Aur, T Vul, κ Pav) the physical and chemical parameters are obtained: spectral class, electron pressure, "microturbulent velocity", relative number of atoms in different chemical elements. The variations of this parameters with a phase are investigated.
