Magnetoconvection: the interaction of convection and small scale magnetic fields.
Abstract
Present consensus about the interaction of convection and magnetic fields is reviewed, with special emphasis on the interaction of convection in the solar convection zone with magnetic fields on the scale of granulation and supergranulation. Computer simulations of Boussinesq systems are reviewed, and additional effects due to stratification and radiation are discussed. The particular mechanisms that determine the degree of evacuation of magnetic fields in the solar photosphere are discussed, and some limitations of the "flux tube" concept are pointed out. Finally, some recent results from numerical simulations of convection in a stratified medium with magnetic fields are discussed, and possible consequences for activity in the chromosphere and corona are mentioned.
