  • We present a scenario ("supranova") for the formation of gamma-ray bursts (GRBs) occurring when a supramassive neutron star (SMNS) loses so much angular momentum that centrifugal support against self-gravity becomes impossible, and the star implodes to a black hole. This may be the most baryon-clean environment proposed so far, because the SN explosion in which the SMNS forms sweeps the medium surrounding the remnant, and the quickly spinning remnant loses energy through magnetic dipole… CONTINUE READING
