Abstract

The traditional model which assumed GRBs as originating from a single Black Hole (BH) have been modified by the Binary Driven Hypernova (BdHN) model in which the trigger of the GRB originate from a binary system composed of a 10 solar mass CO core and a 2 solar mass neutron star binary companion. The binary period being as short as minutes to hours. Recent results evidence that the most energetic GRBs may have as precursors a sequence of two types of SN: a pair-SN followed soon after by a more traditional core collapse. All this appear to open the way to two new types of SNe: the Pair-SNe without a remnant and a magnetized-rotating-core collapse leading to the formation of a pulsar. We generalize our previous assumptions, here the possibility of fission of the rapidly rotating CO core is examined. The role of the magnetic field of the CO core are equally examined with the magneto-hydrodynamic associated process, all the way to generate overcritical fields and e+ e- pairs. All this appear to open the way to a new types of SN, much in line with pair-SN models and a significant change from the initial non rotating models. The BdHN are characterized by seven new physics Episodes here all used to formulate the new approach. The substantial modification of each Episode are outlined by a leading order treatment.
