Thermo-centrifugal wind from a rotating magnetic dipole
Abstract
Numerical solutions for axisymmetric thermocentrifugal winds with a dipole magnetic flux distribution on the stellar surface are presented. Parameters of the models are chosen to be those typical for the sun, except for the angular velocity Omega(0), which is increased up to 60 times the solar value. It is shown that the wind is accelerated efficiently in medium-latitude regions, and that the mass-loss rate is high in both the polar and equatorial regions. This quadripolar property is brought about by the dipole source field, and was not seen in previous monopole models.
