Combining Machine Learning with Recurrence Analysis for resonance detection
Ondřej Zelenka, Ondřej Kopáček, Georgios Lukes-Gerakopoulos
The width of a resonance in a nearly integrable system, i.e. in a non-integrable system where chaotic motion is still not prominent, can tell us how a perturbation parameter is dri…
Resonance crossing of a charged body in a magnetized Kerr background: an analogue of extreme mass ratio inspiral
Sajal Mukherjee, Ondrej Kopacek, Georgios Lukes-Gerakopoulos
We investigate resonance crossings of a charged body moving around a Kerr black hole immersed in an external homogeneous magnetic field. This system can serve as an electromagnetic…
Growth of resonances and chaos for a spinning test particle in the Schwarzschild background
Ondřej Zelenka, Georgios Lukes-Gerakopoulos, Vojtěch Witzany +1
Inspirals of stellar mass compact objects into supermassive black holes are known as extreme mass ratio inspirals. In the simplest approximation, the motion of the compact object i…
Regular and chaotic orbits near a massive magnetic dipole
Jiří Kovář, Ondřej Kopáček, Vladimí Karas +1
Within the framework of Bonnor's exact solution describing a massive magnetic dipole, we study the motion of neutral and electrically charged test particles. In dependence on the B…
