Radiative driven MHD wind solutions for Wolf-Rayet stars

A solution for the Wolf-Rayet stars wind is obtained by solving the MHD equations combined with the radiative driven winds formalism. In this model we combine radiation pressure, collimated magnetic fields and centrifugal forces. Non- isotropic mass density distribution is introduced through an exte...
