Charged Kaluza-Klein double-black holes in five dimensions

arXiv:0909.3835 · doi:10.1103/PhysRevD.83.084037

Abstract

Using a solution generating technique based on the symmetries of the dimensionally reduced Lagrangian we derive an exact solution of the Einstein-Maxwell-Dilaton field equations in five dimensions describing a system of two general non-extremally charged static Kaluza-Klein black holes with spherical horizons. We investigate some of its thermodynamic properties and we also show how to recover various known solutions in particular cases.
