Stellar Magnetic Activity and Long Term Luminosity Variations of Late Type Stars. I. On Generalization of Opik's Convection Theory to a Rotating Medium
A generalization of the original Opik's cellular convection theory has been made to accomodate a rotating convective medium. With the use of the formulation a set of rotating model envelopes of the sun and late type main sequence stars have been constructed under three different rotation periods. Their thermal structures are presented and characteristics of their convection are discussed in the context of stellar dynamo. In the present study it is noted that the rotational angular velocity increases inward with depth, and its increase turns out to be about 6% at the bottom of the solar convection zone.
