Magnetohydrodynamics of Accretion Disks

An ACCRETION DISK is a flat formation of gas and dust rotating about a central object and accreting matter inwards by transporting angular momentum outwards, so that the centrifugal support is gradually removed from the fluid parcels. There are three main classes of accretion disks: (i) disks around accreting compact stars (white dwarfs, neutron stars or black holes) in binary systems, (ii) disks...
