英文摘要:

We have found that the introduction of strange quark phase transition in the simulation of the evolution of supernovae results in a stronger shock wave. This is probably due to an increased convective instability in the core. For our range of calculation we found that a first-order strange phase transition can induce explosion in a WW(88) model with a 1.28 M-circle dot iron core (the upper bound for prompt explosion was about 1.1 M-circle dot). Our result supports DAI Zi-gao et al.′s thesis that strange quark phase transition can raise the probability of supernova explosion.
