论文摘要
我们证明，中微子驱动的流出在爆炸的核心 - 折叠超新星具有近临界的特殊特性，也就是说，它们处于形成终止冲击的边缘。就问题的基本参数而言，我们得出了一个新的冲击形成标准：中微子的光度和能量以及原子恒星的特性。该标准提供了对可用数值结果的统一描述，并激发了未来的模拟。近临界的特性使终止的中微子签名震惊了爆炸几秒钟内PNS周围物理状况的敏感诊断。发现沙丘上的预期信号具有统计学意义。
We demonstrate that the neutrino-driven outflows inside exploding core-collapse supernovae possess a special property of near-criticality, that is, they are on the edge of forming termination shocks. We derive a novel criterion for the formation of the shock, in terms of the fundamental parameters of the problem: the neutrino luminosity and energy as well as the properties of the protoneutron star. The criterion provides a unified description of the available numerical results and motivates future simulations. The property of near-criticality makes the neutrino signatures of the termination shocks a sensitive diagnostic of the physical conditions around the PNS several seconds into the explosion. The expected signal at DUNE is found to be statistically significant.
