Emergence of magnetic null points in electro-vacuum magnetospheres of compact objects: The case of a plunging neutron star
Ondřej Kopáček, Tayebeh Tahamtan, Vladimír Karas
Relativistic effects of compact objects onto electromagnetic fields in their vicinity are investigated using the test-field approximation. In particular, we study the possible emer…

Recurrence Analysis as a tool to study chaotic dynamics of extreme mass ratio inspiral in signal with noise
Georgios Lukes-Gerakopoulos, Ondřej Kopáček
Recurrence analysis is a well settled method allowing to discern chaos from order, and determinism from noise. We apply this tool to study time series representing geodesic and ins…

Transition from regular to chaotic motion in black hole magnetospheres
Ondřej Kopáček
Cosmic black holes can act as agents of particle acceleration. We study properties of a system consisting of a rotating black hole immersed in a large-scale organized magnetic fiel…
