Stationary Dilatons with Arbitrary Electromagnetic Field

Abstract

We present two new classes of axisymmetric stationary solutions of the Einstein-Maxwell-Dilaton equations with coupling constant α2=3\alpha^2=3. Both classes are written in terms of two harmonic maps λ\lambda and τ\tau. λ\lambda determines the gravitational potential and τ\tau the electromagnetic one in such a form that we can have an arbitrary electromagnetic field. As examples we generate two solutions with mass (MM), rotation (ss) and scalar (δ\delta) parameters, one with electric charge (qq) another one with magnetic dipole (QQ) parameter. The first solution contains the Kerr metric for q=δ=0q=\delta=0.
