摘要:

研究了吸积物质在球对称黑洞上的微扰反反应,当吸积处于准稳态时。度量系数修正的一般表达式在Eddington-Finkelstein坐标中找到。结果表明,在黑洞视界附近,与能量动量张量的形式无关,对度规的主要修正是Vaidya形式的.与其他解决方案的关系进行了讨论,并提出了具体的例子。

英文摘要:

We study backreaction of accreting matter onto a spherically symmetric black hole in a perturbative way, when accretion is in a quasi-steady state. General expressions for corrections to the metric coefficients are found in the Eddington-Finkelstein coordinates. It is shown that near the horizon of a black hole, independently of the form of the energy-momentum tensor, the leading corrections to the metric are of the Vaidya form. The relation to other solutions is discussed and particular examples are presented.
