dc.descriptionWe note that if the GRB phenomenon follows from the collapse of a massive object forming a black hole and a torus accreting into it, the resulting ejecta can be only related to the mass and angular momentum that characterize the black hole. The opening angle of the fireball then corresponds to a black hole spin. If indeed the fireballs opening angles are as small as recent estimates reported in the literature suggest, then GRB would be produced by almost maximally rotating BH.
