摘　　要：Using the minimal extension of the standard model and considering the charge radius and the anapole moments of a neutrino,we derive analytical expressions for the stellar energy loss rates associated with the production of a neutrino pair e+γ→ve+ve νein hot plasma under three limiting regimes(nondegenerate,intermediate,and degenerate electrons)of the temperature,electron chemical potential,and plasma energy.The obtained results reveal the presence of an extra contribution of approximately 10%based on the considered calculations.
