【摘要】：黑洞吸積被認(rèn)為是活動(dòng)星系核的能量來(lái)源,而研究黑洞吸積最主要的難題是要解釋吸積氣體的角動(dòng)量是如何轉(zhuǎn)移出去的。黑洞吸積盤理論提出通過粘滯力矩轉(zhuǎn)移角動(dòng)量。徑移主導(dǎo)吸積盤模型(advection-dominated accretion flow,簡(jiǎn)稱ADAF)是幾何厚、光學(xué)薄的低吸積率吸積盤模型,它在解釋低光度活動(dòng)星系核的一些觀測(cè)現(xiàn)象時(shí)獲得了很大的成功。近年來(lái),隨著計(jì)算機(jī)技術(shù)的迅猛發(fā)展,數(shù)值模擬在天體物理研究中獲得了廣泛的應(yīng)用,也取得了突破性的進(jìn)展。主要工作是用數(shù)值模擬方法研究ADAF整體解作為初始條件模擬黑洞的吸積過程。
[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.
