Mixing-length theory for pulsating stars

Douglas Owen Gough

Open publisher page 219 citations

Abstract

The mixing length theory of convection is generalized for use in the envelopes of nonrotating, radially pulsating stars by the methods proposed by Gough (1965) and Unno (1967). The essential differences between the physical assumptions made in the two approaches are explained. The detailed formulas required for a linear pulsational-stability analysis of a static star are derived.
