Description
Summary:In this paper, we present and analyze the simplest physically meaningful model for stationary black diholes-a binary configuration of counterrotating Kerr-Newman black holes endowed with opposite electric charges-elaborated in a physical parametrization on the basis of one of the Ernst-Manko-Ruiz equatoriali antisymmetric solutions of the Einstein-Maxwell equations. The model saturates the Gabach-Clement inequality for interacting black holes with struts, and in the absence of rotation, it reduces to the Emparan-Teo electric dihole solution. The physical characteristics of each dihole constituent satisfy identically the well-known Smarr's mass formula.
