摘要：

We present results from general-relativistic (GR) three-dimensional (3D) core-collapse simulations with approximate neutrino transport for three non-rotating progenitors (11.2, 15, and 40 M-circle dot) using different nuclear equations of state (EOSs). We find that the combination of progenitor's higher compactness at bounce, that is a consequence of the use of softer EOS, leads to stronger activity of the standing accretion shock instability (SASI). We confirm previous predication that the SASI produces characteristic time modulations both in neutrino and gravitational-wave (GW) signals. Our results indicate that the correlation of the neutrino and GW signals, if detected, would provide a new signature of the vigorous SASI activity in the supernova core.
