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-star = 0.91 M-circle dot, R-star = 0.78 R-circle dot). The planetary radius is poorly constrained (0.7 < R-p < 1.4 R-Jup),(15). owing to the grazing transit and the low sampling rate of the K2 photometry.(16)
