Restructuring of the envelope for the model with initial damping, similar to Fig. 2. Panel (a) shows the specific entropy in units of Avogadro’s number N_A and the Boltzmann constant k_B, as well as the density. Both quantities are reported at a mass coordinate of 5.5 M_⊙, which is close to the bottom of the convective envelope. The total energy of the convective envelope is shown in panel (b). For comparison, the undamped model is shown as well (same as Fig. 2c and e).
