Geometric albedo as a function of the planet day-side equilibrium temperature. Dashed vertical lines represent the temperature of the planet for i) a perfect heat redistribution to the nightside, T_d = 1746 ± 26 K (left); ii) no thermal circulation in the atmosphere, T_d = 2077 ± 31 K (middle); and iii) a dynamics-free atmosphere where the radiative time scale is shorter than the advective timescale, iii) T_d,max = 2231 ± 33 K (right). The grey band covers the albedo values allowed by the 1-σ uncertainty on the occultation depth which is assumed to be the dominant uncertainty.
