Convective Energy Transport in the Outer Layers of Stars-A Convective Cell Theory.
Abstract
A convective cell model of the motion in the surface layers of stars is described. This cell theory avoids the problems of truncating an infinite series encountered in the usual normal mode analysis of convection. A family of possible models of organized cellular motion is presented. The convective energy flux is then given as an average over an ensemble of these cells. Although the fundamental uncertainty in this theory remains the average size of these cells, it is possible to treat accurately the rapid variation with depth of Cp, K, and Wd. Self-consistent models of the outer convection zones of the sun and a case roughly corresponding to Arcturus are presented.
