Temperature-pressure profile for T_eff = 2268 K, g = 25 m/s² and T_int = 100 K for a solar-composition atmosphere (red), an atmosphere where TiO and VO have been removed from the atmosphere (blue) and and atmosphere where the stellar irradiation is absorbed at the same optical depth as in the case with TiO/VO but where TiO/VO have been removed from the thermal opacities (grey). Our analytical model is shown as plain lines whereas the numerical solution is shown as dashed lines.
