Massive Stellar Evolution, Supernovae and Nucleosynthesis

地球上许多丰富元素的组成成分，包括构成我们身体的那些元素，都是在一颗被称为超新星的大质量恒星的短暂爆炸阶段产生的。首席研究员建议继续他在恒星演化的高级阶段的理论工作，包括超新星爆炸的几个方面。他之前的工作在过去对超新星1987a从蓝超巨星祖先爆炸的理解中起到了关键作用。他的后续研究将集中于为天文学界提供恒星结构的演化模型，改进这些模型所依据的半对流和扩散的物理特性，将超新星爆炸作为一个已被充分理解的恒星风背景下的问题来处理，以及提高核合成反应的“快速”过程速率。

The constituents of many abundant elements on the Earth, including those composing our own bodies, are manufactured during the brief explosion stage of a massive star known as a supernova. The Principal Investigator proposes to continue his theoretical work on the advanced stages of evolution of stars, including several aspects of supernova explosion. His previous work has been pivotal in the past to an understanding of the explosion of the Supernova 1987a from a blue supergiant progenitor. The continuation of his study will focus on providing the astronomical community with evolutionary models of stellar structure, of improving the physics of semiconvection and diffusion on which these models have been based, on treating the explosion of a supernova as a problem in the well-understood context of stellar winds, and on improving the "rapid"-process rates of nucleosynthetic reactions.
