Metric for two equal Kerr black holes
arXiv:1702.05802 · doi:10.1103/PhysRevD.96.104016
Abstract
We show that the exact solution of Einstein's equations describing a system of two aligned identical Kerr black holes separated by a massless strut follows straightforwardly from the extended 2-soliton solution possessing equatorial symmetry, and we give its concise analytic representation in terms of physical parameters.
