SOPHIE velocimetry of Kepler transit candidates: XIX. the transiting temperate giant planet KOI-3680b

Whereas thousands of transiting giant exoplanets are known today, only a few are well characterized with long orbital periods. Here we present KOI-3680b, a new planet in this category. First identified by the Kepler team as a promising candidate from the photometry of the Kepler spacecraft, we estab...
