论文摘要
中微子仍然神秘。例如，允许增强的自我互动（$ν$ si）具有广泛的影响。在核心偏离超新星内的高中微子密度上，$ν$ si应该很重要，但是缺乏可观察到的可观察力。我们表明，$ν$ si使中微子形成一种紧密耦合的流体，在相对论流体动力学下扩展。流出变成爆发或稳态风；这里发生的情况是不确定的。尽管产生中微子的扩散环境可能会更有可能使风能更大，但仍需要进一步的工作来确定何时实现每种情况。在爆发流程的情况下，$ν$ si增加了中微子信号的持续时间，即使对SN 1987a数据的简单分析也具有强大的灵敏度。对于风流案例，我们概述了一些有希望的想法，这些想法可能会导致新的观察力。这些结果结合在一起，是解决$ν$ SI影响超新星的35年历史难题的重要步骤。
Neutrinos remain mysterious. As an example, enhanced self-interactions ($ν$SI), which would have broad implications, are allowed. At the high neutrino densities within core-collapse supernovae, $ν$SI should be important, but robust observables have been lacking. We show that $ν$SI make neutrinos form a tightly coupled fluid that expands under relativistic hydrodynamics. The outflow becomes either a burst or a steady-state wind; which occurs here is uncertain. Though the diffusive environment where neutrinos are produced may make a wind more likely, further work is needed to determine when each case is realized. In the burst-outflow case, $ν$SI increase the duration of the neutrino signal, and even a simple analysis of SN 1987A data has powerful sensitivity. For the wind-outflow case, we outline several promising ideas that may lead to new observables. Combined, these results are important steps towards solving the 35-year-old puzzle of how $ν$SI affect supernovae.
