Regular and chaotic motion in general relativity: The case of an inclined black hole magnetosphere
Ondřej Kopáček, Vladimír Karas
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…
Oblique magnetic fields and the role of frame dragging near rotating black hole
V. Karas, O. Kopacek, D. Kunneriath +1
Magnetic null points can develop near the ergosphere boundary of a rotating black hole by the combined effects of strong gravitational field and the frame-dragging mechanism. The i…
Regular and Chaotic Motion in General Relativity: The Case of a Massive Magnetic Dipole
Ondřej Kopáček, Jiří Kovář, Vladimír Karas +1
Circular motion of particles, dust grains and fluids in the vicinity of compact objects has been investigated as a model for accretion of gaseous and dusty environment. Here we fur…
Inducing chaos by breaking axial symmetry in a black hole magnetosphere
O. Kopáček, V. Karas
While the motion of particles near a rotating, electrically-neutral (Kerr), and charged (Kerr--Newman) black hole is always strictly regular, a perturbation in the gravitational or…
