黑洞光谱和时间特性研究中的双分量平流数值模拟

Numerical Simulations of a Two Component Advective Flow for The Study of the Spectral and Timing Properties of Black Holes

Kinsuk Giri, Sandip K. Chakrabarti

摘要:

双组分平流是理论上最具物理意义的吸积盘。由于粘性是决定性因素,我们研究了粘性应力对非旋转黑洞吸积流的影响。由于吸积流中粘性引起的角动量转移,角动量分布被修正。我们包括冷却效应,并发现开普勒磁盘上的赤道平面和上方和下方的流动仍然子开普勒。这给出了一个完整的图片,到目前为止,形成的两个组成部分平流围绕黑洞。

英文摘要:

Two component advective flows are the most physical accretion disks which arise from theoretical consideration. Since viscosity is the determining factor, we investigate the effects of viscous stresses on accretion flows around a nonrotating black hole. As a consequence of angular momentum transfer by viscosity in an accretion flow, the angular momentum distribution is modified. We include cooling effects and found that a Keplerian disk is produced on the equatorial plane and the flow above and below remains sub Keplerian. This gives a complete picture to date, of the formation of a Two component advective flow around a black hole.
