Semi-empirical model of a stellar envelope in the presence of a magnetic field

Using the UV observations obtained simultaneously with ground base telescopes and with IUE we have computed a model for the envelope of V923 Aql under the hypothesis of the presence of a magnetic field. Due to the influence of it, the plasma co-rotates with the star increasing its azimutal velocity...
