MHD Jets Around Galactic Objects

We present a self-similar, steady-state model describing both amagnetized accretion disc and a magnetohydrodynamic jet. We focus on therole of a hot corona in such a structure. This corona enables the disc tolaunch various types of jets. By considering the energy conservation, we alsopresent a diagnostic of the luminosity of the magnetized disc, which couldexplain some observational signatures of galactic objects.
