The dynamics of accretion discs around galactic and extragalactic black holes may be influenced by their magnetic field. In this paper we generalise the fully relativistic theory of stationary axisymmetric tori in Kerr metric of Abramowicz et al.(1978) by including strong toroidal magnetic field and construct analytic solutions for barotropic tori with constant angular momentum. This developmen...

Article history: Received 2 November 2014 Accepted 5 December 2014 Available online 9 December 2014 Communicated by F. Porcelli A version of extended magnetohydrodynamics (MHD) that incorporates electron inertia is obtained by constructing an action principle. Unlike MHD which freezes in magnetic flux, the present theory freezes in an alternative flux related to the electron canonical momentum....

The dynamics of accretion disks around galactic and extragalactic black holes may be influenced by their magnetic field. In this paper we generalize the fully relativistic theory of stationary axisymmetric tori in Kerr metric of Abramowicz et al.(1978) by including strong toroidal magnetic field. This development is particularly important for the general relativistic computational magnetohydrod...
