Scientific paper

A radiatively driven wind model with azimuthal symmetry is presented. Rotation effects and simulation of viscous forces were included in the motion equations. Distortion of the star as well as gravity darkening were also included in the computations. An application to Be stars leads to mass-flux ratios between equator and pole of the order of 10 and total mass-loss rates in the range between 10 to the -7th and 10 to the -8th solar mass/yr. The envelope models are flattened toward the equator and the wind terminal velocity in that region is comparable to the values attained in the polar direction.
