Abstract
Any formula used to calculate the temperature gradient in a stellar convection zone must be calibrated, for example by evolving 1 M⊙ stellar models to fit the present age, luminosity and effective temperature of the Sun. When this procedure is followed for various convection theories, including those of Öpik and Böhm-Vitense, the corresponding models become almost indistinguishable. In particular, they predict the same depth, around 150 000 km, for the solar convective zone.Keywords
