Planets and stellar activity: hide and seek in the CoRoT-7 system

Deleuil, M.; Moutou, C.; Queloz, D. +12 more

Since the discovery of the transiting super-Earth CoRoT-7b, several investigations have yielded different results for the number and masses of planets present in the system, mainly owing to the star's high level of activity. We re-observed CoRoT-7 in 2012 January with both HARPS and CoRoT, so that we now have the benefit of simultaneous radial-vel…

CoRoT-22 b: a validated 4.9 R_⊕ exoplanet in 10-d orbit

Mazeh, T.; Aigrain, S.; Alonso, R. +37 more

The CoRoT satellite has provided high-precision photometric light curves for more than 163 000 stars and found several hundreds of transiting systems compatible with a planetary scenario. If ground-based velocimetric observations are the best way to identify the actual planets among many possible configurations of eclipsing binary systems, recent …
