Migrating Dynamo Waves and Consequences for Stellar Current Sheets

We study the relation between stellar dynamo-wave propagation and structure of magnetic field. Modeling dynamo waves by well-known Parker migratory dynamo, we vary intensity drivers in order to obtain activity-wave toward Equator (as solar-activity cycle) or towards Poles. match field dynamo-active shell with that surrounding material, using a simple dissipative magneto-hydrodynamic system for transition region. Introducing weak asymmetry hemispheres, phase shifts dipole, quadrupole, octupole components at various distances from star demonstrate several-percent is sufficient realistic solar dipole quadrupole moments. behavior current sheets show poleward-propagating activity it substantially different ones. In particular, conditions which conical propagate opposite directions.
