    Improved non-LTE Balmer-line profiles for hot stars
    Improved non-LTE line formation calculations for hydrogen in O-stars are presented. The calculations are carried out by means of the method recently developed...

    Influence of Thomson Electron Scattering Redistribution on Spectral Line Polarization Formed in Spherically Symmetric Extended and Expanding Atmospheres
    Scattering of line photons by ambient electrons in thermal motion in the stellar atmosphere modifies the wings of both intensity and linear polarization...

    Intrinsic parameters of galactic luminous OB stars
    We present the results of a spectroscopic analysis of 25 galactic luminous OB stars. The gravities are in general lower than previously assumed, especially for...

    Intrinsic parameters of massive OB stars.
    The author presents the results of his observations of stars of type O5 and earlier and shows that inclusion of the line blocking between 228 and 912 A solves...

    IR spectrophotometry of bright carbon stars
    The results of medium resolution (R=600) spectrophotometry of 15 bright carbon stars of class N, obtained in the range of lambda:1 to 4.2 microns, are presented...

    Linear and non-linear limb-darkening coefficients for the photometric bands R I J H K.
    We have computed limb-darkening coefficients for five commonly used near infrared photometric bands, namely R, I, J, H, and K, using the stellar atmosphere...

    Lithium abundances in metal-deficient dwarfs
    New measurements of the lithium abundance in a sample of 37 field dwarfs of low metallicity (-0.6 ≥ [Fe/H] ≥ 3.2) are presented. Combining these observations...
