Motion of charged particles around a scalarized black hole in Kaluza-Klein theory

Abstract

In this article we study the geodesic motion of charged particles in the spacetime of an extremal rotating dyonic black hole in Kaluza-Klein theory. We derive the equations of motion and present their analytical solutions in terns of elliptic and hyperelliptic functions. Furthermore, we analyze the geodesic motions with the help of parametric diagrams and effective potentials.
