Notes. All quantities were extracted and temporally averaged from at least 250 snapshots in the last half of the simulation. Teff is derived from the temporal and spatial average of the emergent flux. The characteristic size, decay time and relative intensity contrast (δIrms/ ⟨I⟩) of the granulation were computed from intensity maps using the definitions given in Tremblay et al. (2013b). Pbot is the pressure at the bottom layer, Pphot the pressure at τR = 1, and the computation time t is in stellar time not including the initial 2D runs for cooler models. The turnover or advective timescale (tadv) is evaluated at τR = 1. For depth dependent quantities, the spatial average was performed over constant Rosseland optical depth.

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.
