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.
