不等反转黑洞二元系统的精确解

Exact solution for a binary system of unequal counter-rotating black holes

I. Cabrera-Munguia, Claus Lämmerzahl, Alfredo Macías

摘要:

本文给出了一个描述两个不等反旋黑洞之间有一个无质量支柱的双星系统的完整解。它可以用四个任意的参数来表示:代表黑洞视界σ 1和σ 2的两个杆的半长,总质量M,视界中心之间的相对距离R。该解的物理参数的显式形式,即,科马尔质量M1和M2,每单位质量的科马尔角动量a1和a2(a1和a2符号相反),以及坐标距离R,使我们得到一个4参数解的子类,其中一组5个物理参数满足一个简单的代数关系。此外,由支柱提供的黑洞之间的相互作用力的结果是相同的形式,因为它是静态的双史瓦西情况。

英文摘要:

A complete solution describing a binary system constituted by two unequal counter-rotating black holes with a massless strut inbetween is presented. It is expressed in terms of four arbitrary parameters: the half length of the two rods representing the black hole horizons sigma1 and sigma2, the total mass M, and the relative distance R between the centers of the horizons. The explicit form of this solution in terms of physical parameters, i.e., the Komar masses M1 and M2, the Komar angular momenta per unit mass a1 and a2, having a1 and a2 opposite signs, and the coordinate distance R, led us to a 4-parameter subclass of solutions in which a set of five physical parameters satisfy a simple algebraic relation. Moreover, the interaction force, provided by the strut, between the black holes results to be of same form as it is for the static double-Schwarzschild case.
