Abstract (from CDS):

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}¶={1.000}{-0.067}^{+0.071} RJ and a mass of {M}¶={0.613}{-0.026}^{+0.027} MJ. Its host star exhibits significant rotational variability, and we measure a rotation period of ¶_rot=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}¶={1.039}{-0.051}^{+0.050} RJ and a mass of {M}¶={0.579}{-0.027}^{+0.028} MJ. The star has a low metallicity for a hot Jupiter host, [Fe/H]=-0.15±0.05 .
