SOPHIE velocimetry of Kepler transit candidates: X KOI-142c: first radial velocity confirmation of a non-transiting exoplanet discovered by transit timing

S. C. C. Barros, R. F. Diaz, A. Santerne +9

The exoplanet KOI-142b (Kepler-88b) shows transit timing variations (TTVs) with a semi-amplitude of $\sim 12$ hours, earning the nickname of "king of transit variations". Only th…
