the Wolf-Rayet star is always the least massive star of the binary system (in those
cases when two spectra are observed) make it seem probable that, the ...

Stellar Spectral Classification
The minimum mass a star must have to be a Wolf-Rayet progenitor is about 25
MO, but a typical Wolf-Rayet star has a mass in the range 10-25MO. The
discrepancy is due to the massive winds of both the Wolf-Rayet stars and their
progenitors, ...

Massive Stars in Starbursts: Proceedings of the Massive ...
G. Koenigsberger: I'm afraid, now I'm thoroughly confused about how you get a
Wolf-Rayet star. We have three mass-loss episodes: (i) the mass-loss rate of the
progenitor, (ii) some sort of abrupt mass loss where a large fraction of mass is lost

Their extreme temperatures cause them to gradually evaporate, so that their
outer layers stream out into space at a furious rate. For a typical Wolf-Rayet star,
this “stellar wind” travels out from the star at speeds well in excess of 6 million
miles ...
