The effect of the intrinsic effective temperature on the T − P profile of the atmosphere on the day side. D-stands for day, numbers give the effective temperature in K and the core entropy, respectively. Circles mark the top of the convection zone. Notice that for higher effective temperatures the convection zone starts at lower pressures (densities) but at about the same temperatures. Consequently, given the relation from Fig. 1, models with higher intrinsic effective temperature have higher core entropy.
