Metal-Poor Type II Cepheids with Periods Less Than Three Days
V. Kovtyukh, G. Wallerstein, I. Yegorova +6
We have analysed 10 high resolution spectra of Type II Cepheids with periods less than 3 days. We find that they clearly separate into two groups: those with near or slightly below…

Reddenings of FGK supergiants and classical Cepheids from spectroscopic data
V. V. Kovtyukh, C. Soubiran, R. E. Luck +4
Accurate and homogeneous atmospheric parameters (Teff, log (g), Vt, [Fe/H]) are derived for 74 FGK non-variable supergiants from high-resolution, high signal-to-noise ratio, echell…

High precision effective temperatures for 181 F--K dwarfs from line-depth ratios
V. V. Kovtyukh, C. Soubiran, S. I. Belik +1
Line depth ratios measured on high resolution (R=42000), high S/N echelle spectra are used for the determination of precise effective temperatures of 181 F,G,K Main Sequence stars…
