Magnetohydrodynamical Simulations of Black Hole Accretion

摘要Hawley和Balbus正在对引力作用下的致密天体周围的轨道气体进行详细的理论和计算研究。 他们的方法将包括在三维磁流体动力学框架中的黑洞吸积盘的数值模拟和解析解。 后者是必不可少的，因为磁场和相对论力的吸积盘上的压倒性影响进行研究。 该项目的主要重点是为黑洞吸积盘开发一个真实模型网格，最终可将地面和空间观测与之进行比较，该项目的资金由美国国家科学基金会的恒星天文学天体物理学（AST/SAA）和河外天文学宇宙学（AST/EXC）方案提供。

ABSTRACTHawley, John"Magnetohydrodynamical Simulations of Black Hole Accretion"AST-0070979Hawley and Balbus are conducting a detailed theoretical and computational study of orbiting gas around gravitating compact objects. Their approach will include both numerical simulations and analytic solutions for black hole accretion disks in a 3-dimensional magnetohydrodynamical framework. The latter is essential because of the overwhelming influence of magnetic fields and relativistic forces on the accretion disks to be studied. The principle focus of this project will be on developing a grid of realistic models for black hole accretion disks to which ground- and space-based observations can ultimately be compared.Funding for this project was provided by the NSF programs for Stellar Astronomy & Astrophysics (AST/SAA) and Extragalactic Astronomy & Cosmology (AST/EXC).
