Standing accretion shock instability: numericalsimulations of core-collapse supernova

摘要

Standing accretion shock instability (SASI) is one of the candidates to solve thernmystery of why we cannot reproduce the explosion with the present core-collapse supernovarnmodels. We have studied this phenomenon with including neutrino heating and realistic EOSrnand found that SASI may enhance neutrino heating. Although g-mode of proto-neutron star mayrnenhance the SASI growth, the simulations just including the pressure perturbation as a mimicrnof g-mode induced sound wave reveal no signi?cant e?ect on the shock dynamics. Moreover, werndiscuss the required conditions toward the possible laboratory experiment of SASI.
