Scientific paper

The dependence of the wind parameters on the properties of the parent star is investigated by means of an approximate analytical approach. In particular, using a polytropic stellar model and line driving as the mechanism for accelerating the wind, it is shown that mass loss from WR stars can be characterized just by the total mass. The existence of a correlation between mass and mass loss rate, which is close to that one found by Abbott et al. (1986) for WR stars in binary systems, seems to be an intrinsic feature of radiative wind acceleration in He-burning stars.
