Analytic force-free jet from disk-fed rotating black holes
Abstract
We present a new analytic model of a force-free electromagnetic jet launched from a disk-fed rotating black hole. The jet solution is force-free to first order in the black hole spin and is obtained through a systematic construction based on previously developed analytical methods. The black hole jet modeled here exhibits an asymptotically parabolic structure and is parametrized by the location of the current concentration and sign reversal in the disk. We find that the jet properties show negligible dependence on the disk parameter, suggesting a possible universality of slowly rotating black hole jets with respect to disk structure. Our jet model reproduces the key features expected from the Blandford-Znajek mechanism.
