随着银河系核心坍缩超新星的无数探测事件，当前和未来的中微子探测器将能够采样详细的，随时间变化的中微子通量和光谱。这为从中微子信号的各个阶段推断超新星物理学提供了巨大的可能性，从中子化爆发到吸积和早期爆炸阶段再到冷却阶段。该信号将约束年轻原中子星星的质量、半径等体参数的时间演化以及前身星的结构，探测超新星核心的多维现象，并约束早期爆炸阶段的动力学。除了进一步的天体物理学意义，超新星中微子也可能进一步阐明超核密度物质的性质和粒子物理学中的未决问题。
With myriads of detection events from a prospective Galactic core-collapse supernova, current and future neutrino detectors will be able to sample detailed, time-dependent neutrino fluxes and spectra. This offers enormous possibilities for inferring supernova physics from the various phases of the neutrino signal from the neutronization burst through the accretion and early explosion phase to the cooling phase. The signal will constrain the time evolution of bulk parameters of the young proto-neutron star like its mass and radius as well as the structure of the progenitor, probe multi-dimensional phenomena in the supernova core, and constrain thedynamics of the early explosion phase. Aside from further astrophysical implications, supernova neutrinos may also shed further light on the properties of matter at supranuclear densities and on open problems in particle physics.
