Based on the so-called standard model for expanding atmospheres, non-LTE model calculations have been developed during the last years. Their application for the quantitative spectral analysis of WR stars is in progress. Recent results about the parameters and chemical composition of WR atmospheres are reviewed.

The Wolf-Rayet stars and mass loss
Astrophysics and Space Science, 1969Wolf-Rayet stars are defined, a summary is given of the properties of Wolf-Rayet stars, and a qualitative model of a Wolf-Rayet star is sketched. It is incontrovertible that Wolf-Rayet stars are losing mass, a typical rate of mass loss being near 10-5 M ⊙ per year.

Wolf-Rayet stars represent an important stage in the evolution of massive stars, but are only poorly understood so far. For a better knowledge one might determine their effective temperatures, luminosities and atmospheric compositions. But the emission-line dominated Wolf-Rayet spectra were not accessible to a quantitative analysis for a long time ...
