Perturbation Effects of Ion Screening to Leptons in Type-II Supernova

Based on the new progenitor stars model, the influence of ion screening isinvestigated. The simulation results show that ion screening has weakperturbation effects to the leptons in type-II supernova explosion. Ionscreening decreases slightly the fraction of leptons and prolongs slightly theshock propagation time. Moreover, simulation results are shown that ionscreening increases the total energy loss and reduces the shock energy,eventually decreasing of explosion energy and becomes a negative factor tosupernova explosion. In addition, comparison of slight perturbated variationof ion screening to leptons, but simulation results show that ion screeningaffects obviously explosion energy of type-II supernova, hence, it can alsoconfirm that the variation of leptons is very sensitive to energy insupernova explosion.
