We report the discovery from K2 of two transiting hot Jupiter systems. K2-295
(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 K2-295 b has a
similar mass to Saturn, while K2-237 b is a little more massive than Jupiter.
