Structure evolution diagrams similar to Fig. E.1. Colors show the temperature T in panel (a), the first adiabatic index Γ₁ = (∂lnP/∂lnρ)_s in panel (b), the density ρ in panel (c), the absolute radial velocity in units of the convective velocity v_conv in panel (d), the total pressure P in panel (e), the radial velocity in panel (f), the fraction of the radiation pressure P_rad of the total pressure in panel (g), and the velocity divergence ∇ ⋅ v in panel (h).
