Could CoRoT-7b and Kepler-10b be remnants of evaporated gas or ice giants?

► We model the thermal mass loss of CoRoT-7b and Kepler-10b over their lifetimes. ► Planetary density and orbital distance are key parameters for thermal mass loss. ► CoRoT-7b and Kepler-10b cannot be thermally evaporated remnants of hot gas giants. ► A hot Uranus-type planet as origin of CoRoT-7b and Kepler-10b is very unlikely.
