Upperpanel: rotation period of CoRoT-7 vs. the time as obtained from our model of the stellar angular momentum and tidal evolution introduced in Sect. 2.9. The vertical dotted line marks the time corresponding to the presently measured mean rotation period of the star that should correspond to its age in the hypothesis that its rotational evolution followed our model. Lower panel: orbital period of CoRoT-7b vs. the time as computed with our tidal model in Sect. 2.9. The vertical dotted line marks the current value of the orbital period.
