Modeling of the interface between the radiative zone an the convective zone. rb corresponds to the radius at the base of the convective envelope as given by the Schwarzschild’s criterion, Lp is the penetration length over which the plume is decelerated and generates waves, d denotes the extent of the transition region (where the plume velocity is negligible compared to Vb, its value at the entry of the penetration region) and rd is the radius at the top of the radiative zone.

Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.

Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.
