Comment on "Generalized near horizon extreme binary black hole geometry"
arXiv:1909.04820 · doi:10.1103/PhysRevD.100.128501
Abstract
It is demonstrated that the near-horizon geometry of two extreme Kerr black holes of equal mass, which are held a finite distance apart by a massless strut, introduced recently in [Phys. Rev. D 100 (2019) 044033], is a particular member of the near horizon Kerr-Bolt class.
