Theoretical Investigations of the Core-Collapse Supernova Mechanism

伯罗斯博士继续他的理论研究的物理和机制的核心坍缩超新星。他将改进中微子输运和多维效应的处理，以确定它们在核坍缩机制中的作用。通过将他之前的工作扩展到考虑一系列祖星质量，他将研究祖星结构对爆炸延迟、爆炸能量、质量切割和喷射电子分数等特征的系统影响。此外，他将研究r过程重元素核合成发生在超新星爆炸后期恒星的风中，通过详细模拟核合成对风特性的依赖。他还将探索核心本身的不对称性可能对核心坍缩及其特征（引力波和中微子）产生的影响。＊＊＊

Burrows, Adam AST 96-17494 Dr. Burrows continues his theoretical investigations into the physics and the mechanisms of core- collapse supernovae. He will refine the treatment of neutrino transport and multi-dimensional effects to determine their roles in the mechanism of core-collapse. By extending his previous work to consider a range of progenitor masses, he will investigate the systematic effects the structure of the progenitor star has on features such as the delay to explosion, the explosion energy, the mass cut and the ejecta electron fractions. In addition, he will investigate the hypothesis that r-process heavy element nucleosynthesis occurs in the wind from the star late in the supernovae explosion by detailed modeling of the dependence of nucleosynthesis to wind properties. He will also explore the effects that asymmetries in the core itself may have on both the core collapse and its signature as gravitational waves and neutrinos. ***
