Update : HARPS radial velocity data shown at the Boston transit conference (May 2008) seem to indicate that the putative 5 Mearth planet is not there (might have been mistaken for stellar activity). However, all the perturbative analysis done is still valid, meanning that the perturber responsible for the excentricity might be of smaller mass and yet to be directly detected. Stay tuned.
