Abstract:
We report the first disclosure of the planetary nature of
Kepler-432 b (aka Kepler object of interest KOI-1299.01). We
accurately constrained its mass and eccentricity by high-precision
radial velocity measurements obtained with the CAFE spectrograph at
the CAHA 2.2-m telescope. By a simultaneous fit of these new data and
Kepler photometry, we found that KOI-1299 b is a dense transiting
exoplanet, having a mass of Mp=4.87±0.48MJup and radius of
Rp=1.120±0.036RJup. The planet revolves around a K giant star,
ascending the red giant branch, every 52.5d, moving on a highly
eccentric orbit with e=0.535±0.030. By analysing two NIR
high-resolution images, we found that a star occurs at 1:100 from
Kepler-432, but it is too faint to cause significant effects on the
transit depth. Together with Kepler-56 and Kepler-91, KOI-1299
occupies an almost-desert region of parameter space, which is
important to constrain the evolutionary processes of planetary
systems.
