Lately, several observational facts suggest that the long Gamma Ray Bursts (GRB) are related to a certain type of supernovae: the Type Ic supernovae. These are probably due to the sudden death of a Wolf-Rayet star. Some recent models show that the emission of gamma radiation by GRB is provoked by the infall of the matter from an accretion disk on a fast rotating black hole.
The scope of my work is to test, with the Geneva stellar evolution code, wether one can obtain stellar cores in sufficiently fast rotation so that one can generate GRBs. This will be done in taking into account the role of magnetic fields inside the star and of anisotropical mass loss.
