Charged particle dynamics in magnetosphere generated by current loop around Schwarzschild black hole
Martin KoloÅ¡, David KofroÅ
We present a theoretical study of the magnetic field generated by a toroidal current loop situated in the equatorial plane of a non-rotating Schwarzschild black hole, based on the…
Precision tests of analytical tail-term approximations for radiation reaction in Schwarzschild spacetime
Bakhtinur Juraev, Arman Tursunov, ZdenÄk StuchlÃk +2
We investigate the consistency and precision of approximate analytical expressions for the electromagnetic self-force acting on a charged particle in Schwarzschild spacetime endowe…
Electromagnetic radiation-reaction near black holes: orbital widening and the role of the tail
Bakhtinur Juraev, Arman Tursunov, ZdenÄk StuchlÃk +2
We investigate the orbital evolution of a classical charged particle around a Schwarzschild black hole immersed in an external, uniform magnetic field, taking into full account bot…
Interaction of Black Hole Magnetospheres with Inclined Ambient Fields
Madina Zhakipova, Arman Tursunov, Saken Toktarbay +1
Magnetic fields play a central role in black hole astrophysics, powering relativistic jets and other energetic phenomena. While near-horizon magnetic field is usually assumed to or…
Circular equatorial orbits of extended bodies with spin-induced quadrupole around a Kerr black hole: Comparing spin-supplementary conditions
Misbah Shahzadi, Georgios Lukes-Gerakopoulos, Martin Kološ
The worldline of an extended body in curved spacetime can be described by the Mathisson-Papapetrou-Dixon equations when its centroid, i.e., its center of mass, is fixed by a spin s…
Radiative Back-Reaction on Charged Particle Motion in the Dipole Magnetosphere of Neutron Stars
ZdenÄk StuchlÃk, Jaroslav Vrba, Martin KoloÅ¡ +1
The motion of charged particles under the Lorentz force in the magnetosphere of neutron stars, represented by a dipole field in the Schwarzschild spacetime, can be determined by an…
