摘要:

本文导出了描述两个被无质量支杆隔开的反旋全同Kerr黑洞的全度规的显式解析形式。它包含三个任意参数,即其中一个黑洞的Komar质量M、单位质量的Komar角动量a(另一个黑洞具有相同的质量和相等但相反的角动量)和视界中心之间的坐标距离R。在极限的黑洞,度规成为一个特殊的成员Kinnersly-Chitre五参数家庭的真空解决方案推广Tomimatsu-Sato三角洲=2时空,我们提出了完整的一套度量场定义这个限制。

英文摘要:

The full metric describing two counter-rotating identical Kerr black holes separated by a massless strut is derived in the explicit analytical form. It contains three arbitrary parameters which are the Komar mass M, Komar angular momentum per unit mass a of one of the black holes (the other has the same mass and equal but opposite angular momentum) and the coordinate distance R between the centers of the horizons. In the limit of extreme black holes, the metric becomes a special member of the Kinnersly-Chitre five-parameter family of vacuum solutions generalizing the Tomimatsu-Sato delta=2 spacetime, and we present the complete set of metrical fields defining this limit.
