Density and temperature structure of the QHP model described in Section 5.2 and Table 2. The x-axis shows the radius in au, the y-axis the height divided by the radius. The colors of the top plots indicate the mass density, the colors of the bottom plot the temperature. QHPs are located at 0.8 au in a very narrow (0.04 au) ring. The optical depth at the observation wavelength is indicated by the radial (dotted line) τ = 1 surface. Themagenta dashed line represents the sublimation radius of the system. The dark red color in the temperature plot refers only to the location of the QHPs and not their temperature, since QHPs do not have an equilibrium temperaturevalue.
