摘要

研究了热致密磁化物质中与核心坍缩超新星爆炸中质子中子星包层相对应的中微子动力学。得到了考虑核粒子非弹性散射的中微子相空间分布函数的动力学方程。利用输运性质研究了动量空间中的传递分量。当中微子能量超过物质温度的4倍时,能量传递系数由正变为负。在中微子球附近,这种效应会导致中微子光谱中的能量增强。正如本文所证明的那样,这种性质有利于使用大体积中微子望远镜观测超新星中微子通量的可能性。

Effect of Protoneutron Star Magnetized Envelops in Neutrino Energy Spectra
The neutrino dynamics in hot and dense magnetized matter, which corresponds with protoneutron star envelopes in the core collapse supernova explosions, is considered. The kinetic equation for a neutrino phase space distribution function is obtained, taking into account inelastic scattering by nuclear particles. The transfer component in a momentum space using transport properties is studied. The energy transfer coefficient is shown to change from positive to negative values when the neutrino energy exceeds four times the matter temperature. In the vicinity of a neutrino sphere, such effects are illustrated to lead to the energy strengthening in the neutrino spectra. As this paper demonstrates, such a property is favorable for the possibility of observing supernova neutrino fluxes using Large Volume Neutrino Telescopes.
