论文摘要
一些巨大的恒星以\ textit {失败}核心爆发超新星（CCSNE）的身份结束了生命，并变成黑洞（BHS）。尽管在这类现象中，停滞的超新星冲击没有恢复，但外部恒星包膜仍然可以部分弹出。之所以发生这种情况，是因为由于中微子的发射，恒星的流体动力平衡受到了原子恒星（PNS）的重力质量损失的破坏。我们开发了一个简单的模型，该模型模拟PNS的演化及其中微子发射，并使用它来模拟球形对称性中的失败CCSNE，以适用于广泛的祖细胞。我们的模型使我们能够研究失败的CCSNE的质量射击，其中PNS在$ \ sim100 \，{\ rm MS} $中倒入BH中，最多$ \ sim10^6 \，{\ rm s} $。我们对262个不同的SN祖细胞进行了失败的CCSNE模拟，并确定喷射的能量和质量如何取决于祖细胞性质和密集物质的状态（EOS）方程。如果未来的CCSN观察失败，我们在模拟中获得的趋势可用于对BH地层时间时的SN祖细胞特征，EOS和PNS属性施加约束。
Some massive stars end their lives as \textit{failed} core-collapse supernovae (CCSNe) and become black holes (BHs). Although in this class of phenomena the stalled supernova shock is not revived, the outer stellar envelope can still be partially ejected. This occurs because the hydrodynamic equilibrium of the star is disrupted by the gravitational mass loss of the protoneutron star (PNS) due to neutrino emission. We develop a simple model that emulates PNS evolution and its neutrino emission and use it to simulate failed CCSNe in spherical symmetry for a wide range of progenitor stars. Our model allows us to study mass ejection of failed CCSNe where the PNS collapses into a BH within $\sim100\,{\rm ms}$ and up to $\sim10^6\,{\rm s}$. We perform failed CCSNe simulations for 262 different pre-SN progenitors and determine how the energy and mass of the ejecta depend on progenitor properties and the equation of state (EOS) of dense matter. In the case of a future failed CCSN observation, the trends obtained in our simulations can be used to place constraints on the pre-SN progenitor characteristics, the EOS, and on PNS properties at BH formation time.
