Corotating dyonic binary black holes

This paper is dedicated to derive and study binary systems of identical corotating dyonic black holes separated by a massless strut-two 5-parametric corotating binary black hole models endowed with both electric and magnetic charges-where the dyonic black holes carrying equal/opposite electromagnetic charges in the first/second model satisfy the extended Smarr formula for the mass including the magnetic charge as a fourth conserved parameter.
