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. ***

伯罗斯，亚当AST 96-17494 伯罗斯博士继续他的理论研究的物理和机制的核心崩溃超新星。 他将完善中微子运输和多维的治疗 影响，以确定其作用的核心崩溃的机制。通过延长他以前的 工作考虑一系列的祖先群众，他将调查系统的影响， 祖星星的结构没有爆炸延迟、爆炸 能量、质量切割和喷射物电子分数。 此外，他还将调查 r-过程重元素核合成发生在2000年晚些时候来自星星风中的假说 通过详细模拟核合成对风的依赖性来研究超新星爆炸 特性. 他还将探讨核心本身的不对称性对两者的影响 地核坍缩及其引力波和中微子的特征。 ***
