Abstract:

Effects of the neutrino trapping and the temperature, TC, and/or mass of iron cores, M, on the mass ejection of neutrino-trapping supernovae are investigated with the aid of an idealized equation of state on the assumption of adiabatic collapse. It is found that 1) for a fixed TC and/or M, the final stages of the collapse of Fe-cores are classified into the following three cases according to the trapped lepton fraction, YL; in the increasing order of YL, i) no ejection, ii) mass ejection due to the thermal expansion and iii) mass ejection by shock waves. 2) The critical values of YL distinguishing these cases increase with TC and/or M. Therefore, if we adopt the value of the trapped lepton fraction YL=0.39, only cores less massive than 1.4 M⊙ can make violent explosions. The physical interpretation of the above results and the detailed dependence of mass ejection on TC and/or M are discussed.
