Scattering of line photons by ambient electrons in thermal motion in the stellar atmosphere modifies the wings of both intensity and linear polarization...

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...

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...

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...

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...

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...

The lithium abundance in 26 T Tauri stars is derived using data taken at the Isaac Newton Telescope and data from literature. The aim is to understand the...
