The convective envelope in γ Doradus stars: theoretical uncertainties

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 γ Dor pulsators. In this paper 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.
