An independent validation of COROT-7b as a planet is supplied by follow-up performed with the space based Spitzer telescope. Its observations confirmed the transits of the planet, with the same depth, at different wavelengths than the ones observed by COROT. The data then allows to validate COROT-7b as a bona-fide planet with a very high degree of confidence, independently from the noisy radial velocity data.
