AST-0206111PI WoosleyThis project will continue research into nucleosynthesis and the end points of massive stellar evolution. This includes the evolution of stars eight times as massive as the sun and greater through all stages of their lives; modeling their explosions as supernovae, calculating the detailed production of the isotopes of all the elements; and examining the properties of the neutron stars and black holes they leave behind. The output from these calculations will be important input to other studies of the chemical evolution of our Galaxy and other galaxies. As a byproduct, the approximate distribution of neutron star and black hole masses throughout Galactic history will be determined. This project will result in a better understanding of the origin of the elements, the nature of supernovae, and the compositions of stars formed at various epochs in the past. Personnel with valuable computational and scientific skills will be trained. All model results will be made available to the community at the website, www.supersci.org.***

AST-0206111 PI Woosley该项目将继续研究核合成和大质量恒星演化的终点。这包括恒星在其生命的各个阶段的演化，其质量是太阳的八倍或更大;将它们的爆炸建模为超新星，计算所有元素同位素的详细生产;并检查它们留下的中子星和黑洞的性质。 这些计算的结果将成为我们银河系和其他星系化学演化研究的重要投入。作为副产品，整个银河系历史上中子星星和黑洞质量的近似分布将被确定。 该项目将导致更好地了解元素的起源，超新星的性质以及过去不同时期形成的恒星的组成。将培训具有宝贵计算和科学技能的人员。所有模型结果将在网站www.supersci.org * 上提供给社区。
