Title |
Regular and Chaotic Motion in General Relativity: The Case of an Inclined Black Hole Magnetosphere | |||||
Coauthors | Kopacek, Ondrej; Karas, Vladimir | |||||||
Abstract |
Dynamics of charged particles in the vicinity of a rotating black hole embedded in the external large-scale magnetic field is numerically investigated. In particular, we consider a non-axisymmetric model in which the asymptotically uniform magnetic field is inclined with respect to the axis of rotation. We construct the effective potential in a suitable reference frame in order to investigate regions of allowed motion. Moreover, we study the effect of inclination onto the prevailing dynamic regime of particle motion, i.e. we ask whether the inclined field allows regular trajectories or if instead, the deterministic chaos dominates the motion. To characterize the measure of chaoticness we compute maximal Lyapunov exponents and employ the method of Recurrence Quantification Analysis. |
