【摘要】：黑洞吸积被认为是活动星系核的能量来源,而研究黑洞吸积最主要的难题是要解释吸积气体的角动量是如何转移出去的。黑洞吸积盘理论提出通过粘滞力矩转移角动量。径移主导吸积盘模型(advection-dominated accretion flow,简称ADAF)是几何厚、光学薄的低吸积率吸积盘模型,它在解释低光度活动星系核的一些观测现象时获得了很大的成功。近年来,随着计算机技术的迅猛发展,数值模拟在天体物理研究中获得了广泛的应用,也取得了突破性的进展。主要工作是用数值模拟方法研究ADAF整体解作为初始条件模拟黑洞的吸积过程。
[Abstract]:Black hole accretion is considered to be the energy source of active galactic nuclei. The main problem in studying black hole accretion is to explain how the angular momentum of accretion gas is transferred out. The theory of black hole accretion disk puts forward the transfer of angular momentum by viscous moment. The path shift dominant accretion disk model (ADAF) is a low accretion rate accretion disk model with geometric thickness and thin optics. It has achieved great success in explaining some observational phenomena of low luminosity active galactic nuclei. In recent years, with the rapid development of computer technology, numerical simulation has been widely used in the research of astrophysics, and has also made a breakthrough. The main work of this paper is to study the accretion process of black hole with ADAF solution as initial condition.
