Stellar Evolution: The Next Dimension

这一奖项将支持一个理论项目，该项目将对几种恒星类型的内部条件进行建模，在这些类型中，磁场可能起到重要作用。这些恒星是快速自转的A型恒星、低质量的M型恒星和宇宙历史早期形成的恒星。查博耶博士将创建新一代恒星内部模型，在两个空间维度上进行计算，目标是捕捉普通一维模型中缺失的重要物理信息。新的理论模型将广泛提供给社区，从而拓宽建模人员可以利用的软件基础设施。研究生将接受天体物理学和计算方法方面的培训，国际和平研究所将继续进行针对K-8学生的外联工作。

This award will support a theoretical project to model the interior conditions of several stellar types in which magnetic fields may play an important role. These are rapidly rotating A-type stars, low-mass M-type stars, and stars formed early in the history of the universe. Dr. Chaboyer will create a new generation of stellar interior models that perform computations in two spatial dimensions, with the goal of capturing important physics that is missing from common one-dimensional models.The new theoretical models will be made widely available to the community, thereby broadening the software infrastructure that modelers can take advantage of. Graduate students will receive training in astrophysics and computational methods, and the PI will continue ongoing outreach efforts directed at K-8 students.
