ABSTRACT AST-9424416 Ostriker, Jeremiah P. This theoretical research project, directed by Dr. Ostriker, has the objective of elucidating the physical processes occurring in active and quiescent galactic nuclei. While there is general agreement that a proper model will include a dense stellar system and in all likelihood a gaseous disc and one or more massive black holes, the detailed mechanism whereby the prodigious energy output is achieved remains poorly understood. The focus of this research is not on the electrodynamics or relativistic dynamics in the vicinity of a black hole, but on the physical environment in dense stellar systems. Three related areas will be studied: (1) hydrodynamics of time-dependent accretion flows; (2) evolution of dense stellar systems; and (3) the union of the previous two subjects, i.e. physical processes in systems containing both accretion flows and dense stellar systems. ***

摘要 AST-9424416 Ostriker，Jeremiah P. 这一理论研究项目由Ostriker博士指导，目的是阐明活动和静止星系核中发生的物理过程。 虽然人们普遍认为，一个适当的模型将包括一个致密的恒星系统，并在所有的可能性气体盘和一个或多个大质量黑洞，详细的机制，从而实现了巨大的能量输出仍然知之甚少。 研究的重点不是黑洞附近的电动力学或相对论动力学，而是致密恒星系统中的物理环境。将研究三个相关领域：（1）与时间有关的吸积流的流体动力学;（2）致密恒星系统的演化;（3）前两个主题的结合，即同时包含吸积流和致密恒星系统的系统中的物理过程。 ***
