Magnetic fields in the accretion disks for various inner boundary conditions [PDF]
Context. The magnetic fields of accretion disks play an important role in studying their evolution. We may assume that its generation is connected to the dynamo mechanism, which is similar with that in the galactic disks. Aims.
