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…
Oblique magnetic fields and the role of frame dragging
Vladimir Karas, Ondrej Kopacek, Devaky 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 e…
Null Points in the Magnetosphere of a Plunging Neutron Star
Ondřej Kopáček, T. Tahamtan, Vladimír Karas
We explore the structure of a dipole-type vacuum field of a slowly rotating magnetic star near the horizon of a supermassive black hole, where the structure of field lines becomes…
