Postcollapse Evolution of the Cores of Massive Stars

布鲁恩将继续他关于大质量恒星坍缩和超新星爆炸的理论研究。重要的是状态方程的改进和对中微子在维持向外移动的激波中的作用的更好理解。结果应该是一个可靠的爆炸计算，一直到激波接近表面的时间。超新星爆炸1987A是独一无二的，不仅因为它相对较近且明亮，还因为它产生了可测量的中微子通量，中微子是一种难以捉摸的粒子，它告诉我们太阳深处的内部以及现在正在爆炸的恒星。因此，现在应该改进关于爆炸恒星中中微子的起源和作用的理论。特别是，中微子可能在维持恒星爆炸中发挥重要作用，否则恒星爆炸可能会不引人注目。Bruenn是相关物理学方面的专家，他将继续对超新星爆炸及其中微子进行建模。

Bruenn will continue his theoretical work on the collapse and supernova explosion of a massive star. Important are an improved equation of state and better understanding of the role of neutrinos in sustaining the outward moving shock. The result should be a reliable computation of the explosion all the way to the time when the shock approaches the surface. The supernova explosion 1987A was unique not only because it was relatively near and bright but also because it yielded a measurable flux of neutrinos, the elusive particles that inform us of the deep interiors of the Sun and now of exploding stars. Thus it is now appropriate to improve the theories on the origin and effects of the neutrinos in exploding stars. In particular, the neutrinos may play an important role in sustaining the stellar explosion, which might otherwise falter unspectacularly. Bruenn is an expert in the relevant physics and will continue his modeling of the supernova explosion and its neutrinos.
