Magnetic stellar winds: a 2D generalization of the WeberDavis model.
Abstract
A numerical method is presented to calculate steady, axisymmetric wind models with frozenin magnetic fields. As a straigthforward generalization of the model of Weber and Davis (1967), the wind solution along the magnetic field is obtained by an algebraic Bernoulli equation for the density. The important feature found in the numerical solution is the poleward deflection of the wind flow due to the magnetic force of spiraling field lines. Asymptotic behaviour of the solution at large distances shows that the flow does not become radial but is collimated in the direction of the rotation axis.
