Description

We present a Paczynski-Wiita-like pseudo-Newtonian potential describing the orbits of particles in arbitrary static and spherically symmetric spacetimes, including black hole solutions of alternative theories of gravity. This general prescription differs substantially from a previous one, showing that the association of pseudo-potentials with black hole spacetimes is not unique. [Based on V. Faraoni, S.
