Stellar evolution with rotation X: Wolf-Rayet star populations at solar metallicity

  title={Stellar evolution with rotation X: Wolf-Rayet star populations at solar metallicity},
  author={G. Meynet and A. Maeder},
  journal={Astronomy and Astrophysics},
We examine the properties of Wolf-Rayet (WR) stars predicted by models of rotating stars taking account of the new mass loss rates for O-type stars and WR stars (Vink et al. 2000. 2001; Nugis & Lamers 2000) and of the wind anisotropies induced by rotation. We find that the rotation velocities v of WR stars are modest, i.e. about 50 km s - 1 , not very dependent on the initial ν and masses. For the most massive stars, the evolution of ν is very strongly influenced by the values of the mass loss… Expand
