Magnetic Field Structures Generated by Accretion Disc Dynamo
摘要
Abstract
Magnetic fields play an important role in the structure and evolution of accretion disks. There are strong arguments in favor of the fact that they are related to the action of the dynamo mechanism. The structure of the magnetic field that can be obtained using various approximations is discussed. Particular attention is paid to the possibility of the emergence of essentially non-axisymmetric solutions.
