cds-question@unistra.frmultiple-starssolar-system-planetsspectroscopyWe 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+/-0.48M_Jup_ and radius of Rp=1.120+/-0.036R_Jup_. 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.2015A&A...573L...5Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/573/L5CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/573/L5https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/573/L5http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/573/L5https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/573/L5https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/573/L5http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/573/L5GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/A+A/573/L5/kep432RV and BVS data for Kepler-432 (CAFE MPG 2.2m)recnoRecord number assigned by the VizieR team.
