Profiles for the test simulation of Neptune as a function of logP. The blue curves correspond to Zone A, the orange curves correspond to Zone B, and the black curves to the rocky core. The parameters of the simulation are: a = 30 AU, M_core = 0.85M_pl, M_pl = 1M_nept, L_bol =1 L_⊙, and Y_He = 0.2. Top left: cumulative mass of the planet. Top right: radius of the planet. Bottom left: temperature. Bottom right: optical depth in thermal wavelengths.
