Neutrinos from gravitational stellar collapses
Abstract
The first experimental data in extra-solar neutrino astrophysics are available from February 23, 1987, when SN 1987A was observed in the LMC. In this paper, neutrino emission from a gravitational stellar collapse is discussed, using these new data. The problem of two neutrino bursts, recorded in different underground experiments and separated in time by 4.7 hours, is examined. It is shown that there is no contradiction among the different observations, and some predictions from the current theoretical models should be changed in order to fit all the observations.
