Zusammenfassung: | Relativistic effects of compact objects onto electromagnetic fields in their
vicinity are investigated using the test-field approximation. In particular, we
study the possible emergence of magnetic null points which are astrophysically
relevant for the processes of magnetic reconnection. While the magnetic
reconnection occurs in the presence of plasma and may lead to violent mass
ejection, we show here that strong gravitation of the supermassive black hole
may actively support the process by suitably entangling the field lines even in
the electro-vacuum description. In this contribution we further discuss the
case of a dipole-type magnetic field of the neutron star on the plunging
trajectory to the supermassive black hole. While we have previously shown that
given model in principle admits the formation of magnetic null points, here we
explore whether and where the null points appear for the astrophysically
relevant values of the parameters. |
