Systematic study on the astrophysical phenomena of gravitational collapse of massive stars based on the science of dense matter

通过数值模拟研究了大质量恒星引力坍缩的命运。我们利用密度和温度的极端情况下的核数据来找出微物理的影响。通过系统的研究，我们揭示了黑洞的形成发生在40-50Mun的大质量恒星上。我们发现，向黑洞形成的演化与中微子的短爆发有关，这与超新星中微子的情况不同。我们提出，这种中微子的探测是对中心核内密度极高、温度极高的物质的探测。

We studied the fate of the gravitational collapse of massive stars by the numerical simulations. We utilized the nuclear data for the extreme conditions of density and temperature to find out the influence of the microphysics. We revealed that the black hole formation occurs for massive stars of 40-50Msun by the systematic study. We found that the evolution toward the black hole formation is associated with a short burst of neutrinos, which is different from the case of supernova neutrinos. We proposed that the detection of such neutrinos is a probe to the extremely dense and hot matter inside the central core.
