Geodesic structure of the Born-Infeld black hole

In this paper we study the trajectories of test particles in a geometry that is the nonlinear electromagnetic generalization of the Reissner-Nordstrom black hole. The solution was originally derived by Garcia, Salazar and Plebanski (1984 Nuovo Cimento 84 65-90). The studied spacetime is an Einstein-Born-Infeld solution, nonsingular outside a regular event horizon and characterized by three parameters: mass M, charge Q and the Born-Infeld parameter b related to the magnitude of the electric field at the origin. Asymptotically it is a Reissner-Nordstrom solution.
