Abstract

We confirm the planetary nature of two transiting hot Jupiters discovered by the Kepler spacecraft's K2 extended mission in its Campaign 4, using precise radial velocity measurements from FIES @NOT, HARPS-N@TNG, and the coude spectrograph on the McDonald Observatory 2.7 m telescope. K2-29 b (EPIC 211089792b) transits a K1V star with a period of 3.2589263 +/- 0.0000015 days; its orbit is slightly eccentric (e = 0.084(-0.023)(+0.032)). It has a radius of R-p = 1.000(-0.067)(+0.071) R-J and a mass of M-p = 0.6131-0.613-0.026 M-J. Its host star exhibits significant rotational variability, and we measure a rotation period of pot = 10.777 +/- 0.031 days. K2-30 b (EPIC 210957318 b) transits a G6V star with a period of 4.098503 +/- 0.000011 days. It has a radius of R-p = 1.039(-0.051)(+0.050) Ri and a mass of M-p = 0.579(-0.027)(+0.028) M-J. The star has a low metallicity for a hot Jupiter host, [Fe/H] = 0.15 +/- 0.05.
