The solar dynamo.
Abstract
The authors discuss the present state of our understanding of the origin of the Sun's magnetic field. They begin with an introduction to the theory of magnetic field generation in rotating, conducting fluids. Next they consider a dilemma that has persisted for some 15 yr, namely the inconsistency of the kinematic and dynamic convection zone dynamo models. A resolution of this dilemma has been suggested by the recent helioseismology observations on the rotation rate as a function of latitude and depth. These observations, together with other observational and theoretical constraints, suggest that the solar dynamo operates not in the convection zone, but rather in a thin layer between the convection zone and the radiative interior. A model of such a dynamo is presented and discussed. The authors conclude by discussing the problems posed by the placement of the dynamo below the convection zone.
