| With very high-precision photometry, the Kepler and CoRoT space missions allowed us to discover and characterize many Jupiter-sized planets with unprecedented precision, thus providing important constraints to models of formation, evolution, and internal structure of giant planets. In a few cases, the observation of the secondary eclipse in Kepler and CoRoT light curves gives also information on their albedo and atmospheric circulation. In addition to the discovery of a few hundreds of giant candidates, the Kepler telescope has found more than two thousands planetary candidates with radius below that of Neptune shedding a new light on studies of internal structure and frequency of small-size planets. Very accurate radial velocities obtained with the new HARPS-N spectrograph at the Telescopio Nazionale Galileo (La Palma) are permitting to unveil the nature and determine the mass of some small-size Kepler candidates. I will present recent works in this context. |
