outbursting black-hole low-mass X-ray binaries. We then turn to the role of advection in accretion flow onto black holes illustrating its action and importance with a toy model describing both ADAFs and slim discs. We conclude with a presentation of the general-relativistic formalism describing...
Black hole, cosmic body of extremely intense gravity from which nothing, not even light, can escape. It can be formed by the death of a massive star wherein its core gravitationally collapses inward upon itself, compressing to a point of zero volume and

We consider the stationary problem of accretion on a nonrotating black hole. Advection is taken into account and used bridging formula for radiative loses at high and low effective optical depths. Investigate the global solutions for the accretion disc, describing the continuous transition between ...

million years. This was very surprising because we had previously thought that such streams should occur only in systems eating at low rates, whereas in those with huge appetites, theblack holeshould be fed through a more ordered and constant flow of matter (usually called `the accretion disc...
从照片上看这是一个中心为黑色的明亮环状结构,黑色部分是黑洞投下的“阴影”(shadow),明亮部分是绕黑洞高速旋转的吸积盘(accretion disk)。网友们还发挥想象将黑洞修图成了甜甜圈的模样。 美国国家航空航天局(NASA)对黑洞的科普是:A black hole is a place in space where gravity pulls so much that even ...
The evolution of black hole accretion disks is investigated by considering both the thin disk accretion and the Blandford Znajek (B Z) process. 在同时考虑薄盘吸积与BlandfordZnajek过程的条件下讨论了黑洞吸积盘的的演化,并指出黑洞的无量纲角动量a 是标志黑洞吸积盘演化特征的重要参量。 更多例句>> ...
The effect of an accretion disk on the Blandford-Znajek process and the evolution of a black hole are discussed using a simplified system for the black hole - accretion disk in which the accretion rate is supposed to be dominated by the strong magnetic field on the disk. The evolutions of...
