Theoretical Studies in Astrophysics

将对理论天体物理学中的一系列不同问题进行研究。将研究六个大领域的专题：(A)星系和星系团；(B)恒星动力学和数值技术；(C)广义相对论和引力辐射的产生；(D)射电脉冲星和致密X射线源物理；(E)星际介质；(F)粒子天体物理学和宇宙学。本课程将强调天体物理学与流体力学、相对论和高能物理领域之间的界线。将根据天体物理学的相关性和物理内容选择特定的问题进行调查。将研究的天体物理对象包括大的、自引力的N体系统(星系团、星系、相对论星团和球状星团)、致密恒星(白矮星、中子星和黑洞)、星际氢和早期宇宙中的密度扰动。分析方法将从相当简单的解析模型构建扩展到大规模的计算机计算。将强调理论和观察之间的密切关系。

Research will be conducted on a diverse array of problems in Theoretical Astrophysics. Topics within six broad areas will be investigated: (A) Galaxies and Galaxy Clusters; (B) Stellar Dynamics and Numerical Techniques; (C) General Relativity and the Generation of Gravitational Radiation; (D) Physics of Radio Pulsars and Compact X-ray Sources; (E) The Interstellar Medium; and (F) Particle Astrophysics and Cosmology. The borderlines between these areas of astrophysics and of hydrodynamics, relativity and high energy physics will be emphasized. Specific problems for investigation will be chosen for their astrophysical relevance and physical content. Astrophysical objects which will be studied include large, self-gravitating, N-body systems (galaxy clusters, galaxies, relativistic star clusters, and globular clusters), compact stars (white dwarfs, neutron stars and black holes), interstellar hydrogen, and density perturbations in the early universe. Methods of analysis will extend from rather simple, analytic model construction to large-scale computer calculations. The close relationship between theory and observation will be emphasized.
