Beschreibungen/Notizen

• ABSTRACT We report the discovery of K2-31b, the first confirmed transiting hot Jupiter detected by the K2 space mission. We combined K2 photometry with FastCam lucky imaging and FIES and HARPS high-resolution spectroscopy to confirm the planetary nature of the transiting object and derived the system parameters. K2-31b is a 1.8-Jupiter-mass planet on a 1.26-day orbit around a G7 V star ( M , R ). The planetary radius is poorly constrained (0.7 < Rp < 1.4 RJup),15 owing to the grazing transit and the low sampling rate of the K2 photometry.16
