Electrogeodesics in the di-hole Majumdar-Papapetrou spacetime
Original language description
We investigate the (electro-)geodesic structure of the Majumdar-Papapetrou solution representing static charged black holes in equilibrium. We assume only two point sources, thus imparting spacetime axial symmetry. We study electrogeodesics both on and off the equatorial plane and explore the stability of circular trajectories via the geodesic deviation equation. In contrast to the classical Newtonian situation, we find regions of spacetime admitting two different angular frequencies for a given radiusof the circular electrogeodesic. We look both at the weak-and near-field limits of the solution. We use analytic as well as numerical methods in our approach.
