Constraints obtained on the age and radius of CoRoT-18b. The colored circles correspond to 1σ (red), 2σ (yellow), or 3σ (blue) solutions. The figure also plots the same constraints for CoRoT-2b (grayscale), when not including the effects of spots (see Czesla et al. 2009; Guillot & Havel 2011). The evolution tracks show the progressive contraction of a 3.5   MJup planet with Teq ~ 1600 K, in the so-called “standard approach”, when increasing atmospheric opacities by a factor 3.5, and when dissipating 1029   erg   s-1 at the center (see Guillot & Havel 2011 for a description of the models).
