Title: Dynamic structure of a stellar envelope under the magnetic induction and radiation fields
Author(s):  M.F. Montero,  A.M. Platzeck (Poster)

In this paper we show a perturbative dinamical analysis of the cool envelope of Be stars under the magnetic induction, radiation and gravitational fields. We consider the magnetohydrostatic model by Ringuelet-Iglesias (RI) as a first order approximation. For small perturbations this method gives a density distribution similar to that obtained by the RI model. When the perturbation is increased, the numerical results show a lower density region at the poles. Nevertheless, we do not obtain a thin disk like other authors.
