Colour maps showing the temperature distribution in the model atmosphere of the 100× solar metallicity simulation from Charnay et al. (2015). The inner white disc represents the inner part of the planet with a radius assumed to be equal to that of GJ 1214 b (17.600 km). Top panel: temperature at the terminator. The planet is seen from the observer during transit, the poles being at the top and bottom. Bottom panel: the star is on the left and the observer on the right on the z = 0 axis. The poles are on the x = 0 axis. From centre outward, the five solid lines are respectively the 106, 103, 1, 10−2, and 10−4 Pa pressure levels. The outer circle is there as an eye guide to highlight the non-sphericity of the planet. Temperature is well homogenised below the ~103 Pa level. Maps are to scale and show that the dayside is noticeably more vertically extended than the nightside.
