the average convective velocity $\vca$ is on the order of 1 to 10$\kms$ for the   FeCZ,   we found that the average convective velocity $\vca$  in the He convective zone is always very low ($\simle ($ \simle  1\kms$). Convection due to hydrogen  recombination is absent; this dominates at lower effective temperatures   than the ones studied here.
