Description

The study of charged test particle dynamic in the combined black hole gravitational field and magnetic field around it could provide important theoretical insight into astrophysical processes around such compact objects. We will examine simple but astrophysically relevant parabolic magnetic field configuration as a toy model for magnetosphere around Schwarzschild black hole. Bounded orbits and their stability will be examined using effective potential approach and the existence of stable charged off-equatorial structures close to axial symmetry axis will be proven. Influence of radiation reaction damping force on particle nonlinear chaotic dynamics will be tested.
