摘要：

We report the first disclosure of the planetary nature of Kepler-432 b (aka Kepler object of interest K01-1299.01). We accurately constrained its mass and eccentricity by high-precision radial velocity measurements obtained with the CAFE spectrograph at the CANA 2.2-m telescope. By simultaneously fitting these new data and Kepler photometry, we found that Kepler-432 b is a dense transiting exoplanet with a mass of M-p = 4.87 +/- 0.48 M-Jup and radius of R-p = 1.120 +/- 0.036 R(Ju)p. The planet revolves cry 52.5 d around a K giant star that ascends the red giant branch, and it moves on a highly eccentric orbit with e = 0.535 +/- 0.030. By analysing two near-1R high-resolution images, we found that a star is located at 1.1 '' from Kepler-432, but it is too faint to cause significant effects on the transit depth. Together with Kepler-56 and Kepler-91, Kepler-432 occupies an almost-desert region of parameter space, which is important for constraining the evolutionary processes of planetary systems.
