Difference of various structural quantities between a model with a modified temperature gradient in the overshooting layer and a reference model calculated with the Lyon stellar evolution code. The temperature gradient in the modified model is changed over a distance d_ov = α_ovH_P, CB below the convective boundary (indicated by the vertical solid line). Lower panel: results for α_ov = 0.15 and upper panel: for α_ov = 0.20.
