Summary, in English

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 1.26-day orbit around a G7 V star (M∗ = 0.91 M⊙, R∗ = 0.78 R⊙). The planetary radius is poorly constrained (0.7<Rp<1.4 RJup), owing to the grazing transit and the low sampling rate of the K2 photometry.16
