The spin-dependence of the Blandford-Znajek effect
The interaction of large scale magnetic fields with the event horizon of rotating black holes (the Blandford-Znajek [1977] mechanism) forms the basis for some models of the most relativistic jets. We explore a scenario in which the central inward “plunging” region of the accretion flow enhances the trapping of large scale poloidal field on the black hole. The study is carried out using a fully ...
متن کاملA Toy Model for Blandford-Znajek Mechanism
A toy model for the Blandford-Znajek mechanism is investigated: a Kerr black hole with a toroidal electric current residing in a thin disk around the black hole in the equatorial plane. The toroidal electric current generates a poloidal magnetic field threading the black hole and disk. The rotation of the black hole and disk relative to the magnetic field induces an electromotive force, which c...

متن کاملActivation of the Blandford-Znajek mechanism in collapsing stars
Collapse of massive stars may result in formation of accreting black holes in their interior. The accreting stellar matter may advect substantial magnetic flux onto the black hole and promote release of its rotational energy via magnetic stresses (the BlandfordZnajek mechanism). In this paper we explore whether this process can explain the stellar explosions and relativistic jets associated wit...
متن کاملStellar explosions powered by the Blandford-Znajek mechanism
In this letter we briefly describe the first results of our numerical study on the possibility of magnetic origin of relativistic jets of long duration gamma ray bursters within the collapsar scenario. We track the collapse of massive rotating stars onto a rotating central black hole using axisymmetric general relativistic magnetohydrodynamic code that utilizes a realistic equation of state of ...
