… that this black hole magnetosphere based on a disk current model has the asymptotically
conical shape of magnetic –eld lines. This asymptotic structure is a consequence of the disk …

… a field held by an accretion disk that extends down to the ISCO of the black hole. In that case,
… The current sheet lies along the equatorial thin disk in the monopole solutions, and along …

… However, such a configuration is meaningful only if there is a massive perfectly conducting
thin disc in the equatorial plane of the black hole. Otherwise, the equatorial current sheet is …

… a stationary axisymmetric force-free degenerate magnetosphere of a rotating Kerr black hole
surrounded by a thin, Keplerian, infinitely conducting accretion disk. We focus on the closed…

… As our first example, we consider a thin disc orbiting at prograde Keplerian angular velocity
|$\omega =(a+r^{3/2}/\sqrt{M})^{-1}$|⁠, up to the innermost stable circular orbit (ISCO). The …

… I study the magnetosphere of a black hole that is connected by the magnetic field to a thin
conducting Keplerian disk. I consider the case of a Schwarzschild black hole only, leaving the …

… with the minimum number of extra elements, namely a surrounding thin disk of matter to …
Charges and currents will be produced through pair production in the black hole magnetosphere…

… We consider a geometrically thin disk with ϵ = 5% and obtain qualitatively similar results
for a thicker … In what follows, we detail the results we obtain with thin disks only. …

… black hole/star and the surrounding thin accretion disc. For a perfectly conducting star, the
field that anchors on the star will always extract significant amount of energy from the star, but …

… magnetosphere of a black hole in the following cascade mechanism: a random particle …
black hole, inverse Compton scattering by the particle of a thermal photon from the accretion disk …
