The convective envelope in gamma Doradus stars: theoretical uncertainties

Abstract

The depth of the convective envelope plays a fundamental role in the driving mechanism proposed by Guzik et al. (2000) to explain the high-order g modes of gamma Dor pulsators. In this poster we study the sensitivity of the convective envelope depth to the description of convective transport, to relevant physical processes, such as microscopic diffusion, and to other uncertainties in theoretical stellar models.
