H. ; Gough, D. O. Abstract The time-dependent mixing-length theory described in the previous abstract has been applied, in the quasi-adiabatic approximation, to a series of models of ~ Cephei stars of 7Mo previously studied by Baker and Kippenhahn (Astrophys. J. 142, 868,1965). The hottest models of this series have negligible surface convection zones, but the coolest models have deep convection zones that include the low-lying hydrogen and helium ionization regions. On the basis of the quasi-adiabatic approximation, which is not valid near the surface of our stellar envelopes, we tentatively conclude that the increasing importance of convection in stars of lower effective temperature is responsible for the return to stability at the cool edge of the Cepheid strip.
