Default temperature-pressure profile of the hot Jupiter (Section 3), self-luminous (Section 4.1), and sub-Neptune planet (Section 4.2), following Guillot (2010). The irradiation temperatures of the hot Jupiter, self-luminous planet, and the sub-Neptune planet are taken to be 500 K, 1000 K, and 300 K, correspondingly. Condensation curves of Mg₂SiO₄, SiO₂, Fe, Al₂O₃ (for hot Jupiter and self-luminous planet), NaCl and ZnS (for sub-Neptune) are shown as colored lines. The solid, dashed, and dotted saturation curves denote solar, 10 times solar, and 100 times solar metallicity, respectively.
