Rediscusión de HD 45677: un modelo magnetohidrodinámico

Abstract

We present a magneto-hydrodynamical model for HD 45677. This star is seen at a large inclination angle and it has an important magnetic held. Therefore, we considered the basic magnetic model of Weber and Davies where we took into account the radiation field and a temperature law given by the temperature of formation of the different ions. The resulting velocity law has been applied to obtain the Hα emission line profile. The calculation of the Hα profile was performed resorting to a rigorous solution of the radiative transfer equation in the comoving-frame. The velocity law obtained reproduces fairly well the observed line velocities.
