The Mass of the First Stars and Black Holes

该项目将支持博士后学者兼研究生S努力开发原始原恒星HII区爆发的辐射流体动力学模拟。这些模型还将包括原恒星自转、WIMP湮没加热和盘光蒸发的影响，为了更好地理解第一批恒星(人口III.1)是如何形成的，这些模型是必要的。这项工作具有更广泛的影响，因为一些研究成果将纳入国际和平研究所的教学和公共宣传活动。第一批恒星的质量上限将是早期宇宙化学演化以及星系和球状星团形成模型的重要输入。

This project will support a postdoctoral scholar and graduate student?s efforts to develop radiation hydrodynamical simulations of HII region breakouts of primordial protostars. These models will also include the effects of protostellar rotation, WIMP annihilation heating, and disk photo-evaporation, and are needed in order to better understand how the first stars (Population III.1) formed. This work has broader impacts in that some research results will be integrated into teaching and public outreach activities of the PI. An upper mass limit of the first stars will be an important input for models of early universe chemical evolution as well as galaxy and globular cluster formation.
