One of these bodies is combined with an axial magnetic field through a compact object to extract energy in the Blandford-Znajek process.
One of these bodies is combined with an axial magnetic field through a compact object to extract energy in the Blandford-Znajek process. The Eddington limit gives the upper bound for the rate of their formation and, hence, characteristic temperature and the formation of one of them around a black hole at the center of a galaxy gives rise to an active galactic nucleus. In cases such as those involving dwarf novae, the gases in these objects behave like highly viscous fluids; these gases are heated by frictional churning as they dissipate angular momentum, a process especially notable in the Roche lobes of certain binary systems. FTP, identify these circular objects formed when material coalesces around a gravitational source.
