1110.0700 (Wen-Biao Han et al.)

Electron and positron pair production in gravitational collapse    [PDF]

Wen-Biao Han, Remo Ruffini, She-Sheng Xue
Neutral stellar core at or over nuclear densities is described by positive charged baryon core and negative charged electron fluid since they possess different masses and interactions. Based on a simplified model of gravitationally collapsing or pulsating baryon core, we approximately integrate the Einstein-Maxwell equations and the equations for the number and energy-momentum conservation of complete degenerate electron fluid. We show possible electric processes that lead to the production of electron-positron pairs in the boundary of baryon core, and calculate electron-positron pair energy. This might be important for understanding the energy source of gamma-ray bursts.
