Each panel shows the T(P) profiles for the clear atmosphere (red line) and cloudy atmosphere (blue line) computed for a sub-Neptune belonging to our sample of eight sub-Neptunes. The phases of the interfaces for TOI-270 d and TOI-1231 b are shown in Figure 5, while those for the rest of the sub-Neptunes in our sample are shown here. Similar to Figure 5, the thicker lines depict the convective regions of the atmosphere. The locus of blue and red crosses shows the P and T locations of the atmosphere–mantle interface computed by coupling our atmospheric model with the interior structure model for the cloudy and clear models, respectively. The P–T location and the T(P) profiles are overlaid on the phase diagram for silicates, depicting its solid and molten phases as blue and red shaded regions.
