A thorough study of the correlation between P1=P0 ratio, fundamental period, and chemical composition (abundances of metals that compose Z) was conducted to investigate the significance of the iron-peak elements on the ratio. The results suggested a

We have achieved more than 80 high-precision relations between M_v, T_eff and iron line-depths ratios. These relations have been used for the estimation of the absolute magnitudes M_v for 43 FGK supergiants with an error 0.05^m–0.25^m. The program

We have determined 28 relations between M ν, T eff and line depths ratios Rλ1/R λ2. These relations have been used for the estimation of the absolute magnitudes M ν of 56 FGK supergiants with an error 0.05-0.30 mag (Table 1). The application rang

We describe an effective method of investigation of the Diffuse Interstellar Bands (DIBs) in the spectra of Cepheid stars. DIBs are believed to originate from the absorption of such carriers as polycyclic aromatic hydrocarbons in the interstellar gas

A large number of high-dispersion spectra of classical Cepheids were obtained in the region of the CaII H+K spectral lines. The analysis of these spectra allowed us to detect the presence of a strong Balmer line, H$\epsilon$, for several Cepheids, in

To identify the pulsation mode of three low-amplitude classical Cepheids, namely V1334 Cyg, V440 Per and V636 Cas, we use absolute magnitudes which are based upon Mv–Fe II/Fe I line depth relations. We determine that V1334 Cyg is pulsating in the f
