Abstract
The energy extraction process from a black hole which is considered at the basis of modeling Gamma-Ray Bursts appear to be mediated by an electron-positron plasma created in an overcritical electric field. The role of the Thomas-Permi approach in Neutron Star matter cores is presented and discussed with special attention to solutions globally neutral and not fulfilling the traditional condition of local charge neutrality. A new stable configuration is found with a field well above the critical value, confined to a shell close to the surface with a thickness of a few electron Compton wavelength. This new solution can be of relevance in understanding unsolved issues of the gravitational collapse processes and their energetics leading to the formation of a Kerr-Newman black hole. © 2008 American Institute of Physics.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
