EPIC 220501947 b and K2-237 b: two transiting hot Jupiters
We report the discovery from K2 of two transiting hot Jupiter systems. EPIC 220501947 (observed in Campaign 8) is a K5 dwarf which hosts a planet slightly smaller than Jupiter, orbiting with a period of 4.0 d. We have made an independent discovery of K2-237 b (Campaign 11), which orbits an F6 dwarf every 2.2 d and has an inflated radius 50 - 60 per cent larger than that of Jupiter. We use high-precision radial velocity measurements, obtained using the HARPS and FIES spectrographs, to measure the planetary masses. We find that EPIC 220501947 b has a similar mass to Saturn, while K2-237 b is a little more massive than Jupiter.
