Proposal ID: AST-0239709Institution: Pennsylvania State University PI: Abel, TomDr. Tom Abel will use his CAREER award at the Pennsylvania State University to directly calculate the formation and evolution of the first stars in the universe. The primary goals are to realistically simulate the formation of the first stars up to the zero-age main sequence, study their impact on their host galaxies, and derive realistic predications of observable characteristics. Novel numerical techniques, including the addition of three-dimensional radiative transfer into a general adaptive mesh refinement hydrodynamics code, will be developed. The numerical techniques developed for this purpose will be applicable to a multitude of other astrophysical problems such as the formation of Population I and II stars, cosmological reionization, chemical enrichment of the intergalactic medium, galaxy formation, supermassive black hole formation, gamma ray burst afterglows, and supernova remnants. All new numerical codes will be released to the scientific community.In addition to his research, Dr. Abel will continue to produce animations for the public, and develop visualizations for students and the public that make use of state-of-the-art immersive technology. He will also develop courses on numerical astrophysics and cosmology that will train students to apply public N-body and radiation hydrodynamics codes to model a variety of astrophysical phenomena.

提案ID：AST-0239709机构：宾夕法尼亚州立大学PI：Abel，TomDr.汤姆·阿贝尔将利用他在宾夕法尼亚州立大学获得的职业奖直接计算宇宙中第一批恒星的形成和演化。主要目标是真实地模拟第一批恒星的形成，直到零年龄的主序，研究它们对宿主星系的影响，并得出可观测特征的现实预测。将开发新的数值技术，包括在一般自适应网格细化流体力学代码中增加三维辐射转移。为此目的开发的数值技术将适用于许多其他天体物理问题，如人口I和II的恒星的形成，宇宙学再电离，化学富集的星系际介质，星系形成，超大质量黑洞的形成，伽玛射线暴余辉，和超新星遗迹。 所有新的数字代码将向科学界发布。除了他的研究，Abel博士将继续为公众制作动画，并利用最先进的沉浸式技术为学生和公众开发可视化效果。他还将开发数值天体物理学和宇宙学课程，培训学生应用公共N体和辐射流体力学代码来模拟各种天体物理现象。
