Abstract The dynamical properties of an electron–positron–photon plasma created by the vacuum polarization process occurring around a charged gravitationally collapsing core of an initially neutral star are examined within the framework of general relativity and quantum field theory. The Reissner–Nordstrom geometry is assumed to apply between the collapsing core and the oppositely charged remnant of the star. The appearance of a separatrix at radius R , well outside the asymptotic approach to… Expand

We analyze GRB 151027A within the binary-driven hypernova (BdHN) approach, with progenitor a carbon-oxygen core on the verge of a supernova (SN) explosion and a binary companion neutron star (NS).Expand
Electron-positron pair production in space- or time-dependent electric fields
Treating the production of electron and positron pairs by a strong electric field from the vacuum as a quantum tunneling process we derive, in semiclassical approximation, a general expression forExpand
Black Holes, Supernovae and Gamma Ray Bursts
We review recent progress in our understanding of the nature of Gamma Ray Bursts (GRBs) and in particular, of the relationship between short GRBs and long GRBs. The first example of a short GRB isExpand
Gravitational and electric energies in the collapse of a spherical thin-shell capacitor

Electron-positron pair oscillation in spatially inhomogeneous electric fields and radiation
Abstract It is known that strong electric fields produce electron and positron pairs from the vacuum, and due to the back-reaction these pairs oscillate back and forth coherently with the alternatingExpand
