Abstract

Study of a particular case of a 2-soliton solution of the Einstein-Maxwell equations.

A new exact solution of the coupled Einstein-Maxwell equation is given. It is found using the soliton method, adding one soliton to the Schwarzschild background; in this sense it can be considered a `2-soliton' solution. The solution is stationary and axial-symmetric, and has five physical parameters. The physical interpretation we give is that it describes a Kerr-Newman naked singularity linked by a ``strut" to a Schwarzschild black hole. Indeed, on the axis, between the two bodies, it is present an unavoidable conic singularity. Finally, we give the lines of force of the electrical field in three different cases, the main result being the presence of an induced charge over the Schwarzschild horizon.
