A rotating collapsar and possible interpretation of the LSD neutrino signal from SN 1987A

We consider an improved rotational mechanism of the explosion of a collapsing supernova. We show that this mechanism leads to two-stage collapse with a phase difference of ~5 h. Based on this model, we attempt a new interpretation of the events in underground neutrino detectors on February 23, 1987,...

Description
Summary:We consider an improved rotational mechanism of the explosion of a collapsing supernova. We show that this mechanism leads to two-stage collapse with a phase difference of ~5 h. Based on this model, we attempt a new interpretation of the events in underground neutrino detectors on February 23, 1987, related to the supernova SN 1987A.
