We studied the formation of spectral lines at infinity with the redistribution function R1. The radial optical depths considered are 5, 5, 10, 50 and 100. A linear law of velocity is assumed in these calculations. Profiles ...

The analysis of spectroscopic data for 30 Algol-type binaries is presented. All these systems are short period Algols having primaries with spectral types B and A. Dominant spectral lines were identified for the spectra ...
