Tiny charge - small mass - big effect: the onset of chaos near accreting black holes
Abstract
Within the framework of classical General Relativity the motion of particles near a rotating (Kerr) black hole is strictly regular. However, even a small perturbation by the surrounding matter can trigger the onset of chaos. The particle motion and acceleration then exhibit very diverse characteristics and the acceleration efficiency. In this context we examine the role of electric charging and self-gravity of a gaseous/dusty torus in strong gravity of a supermassive black hole magnetosphere. While the central black hole dominates the gravitational field and remains electrically almost neutral, the surrounding material has non-negligible self-gravitational impact on the torus structure and the acceleration of particles in the corona. These influences need to be taken into account to achieve a self-consistent picture.
