Recurrence plots and chaotic motion around Kerr black hole
Ondřej Kopáček, Jiří Kovář, Vladimír Karas +1
We study the motion of charged test particles around a Kerr black hole immersed in the asymptotically uniform magnetic field, concluding that off-equatorial stable orbits are allow…
Transition from Regular to Chaotic Circulation in Magnetized Coronae near Compact Objects
Ondřej Kopáček, Vladimír Karas, Jiří Kovář +1
Accretion onto black holes and compact stars brings material in a zone of strong gravitational and electromagnetic fields. We study dynamical properties of motion of electrically c…
Off-equatorial orbits in strong gravitational fields near compact objects -- II: halo motion around magnetic compact stars and magnetized black holes
Jiri Kovar, Ondrej Kopacek, Vladimir Karas +1
Off-equatorial circular orbits with constant latitudes (halo orbits) of electrically charged particles exist near compact objects. In the previous paper, we discussed this kind of…
