Motion of a charged test particle around a static black hole in a monopole magnetic field
Ken-ichi Nakao, Yota Endo, Hideki Ishihara +4
We study the motion of a charged test particle in the spacetime with a spherically symmetric black hole which is immersed in a monopole magnetic field. We show that the radial moti…

Vacuum Magnetospheres around Kerr Black Holes with a Thin Disk
Yota Endo, Hideki Ishihara, Masaaki Takahashi
We construct a model for stationary and axisymmetric black hole magnetospheres by solving the vacuum Maxwell equations in Kerr backgrounds. The poloidal magnetic field is generated…
