Abstract:
Neutrinos are present in all processes which may take place in astrophysical systems. They are efficient tools at the time of converting gravitational energy into kinetic energy as a way of cooling down self-collapsing objects. We concentrate on the role of neutrinos in GRB progenitors. To explore some consequences upon neutrino observables, like the appearance of decoherence and changes in the oscillation patterns, we have taken into account the interactions between neutrinos and the environment as well as the interaction between neutrinos.
