Description
We present general-relativistic hydrodynamical simulation results of accretion from an orbiting accretion torus (with a cusp) onto a Reissner-Nordström (RN) black hole and a RN naked singularity. The results could not be more different for the two cases. For a black hole, just as in the familiar Kerr/Schwarzschild case, matter overflowing the cusp plunges into the black hole horizon. For the naked singularity, the accreting matter forms an inner structure of toroidal topology and leaves the system via powerful outflows.
