TWO HOT JUPITERS from K2 CAMPAIGN 4
(2016) In Astronomical Journal 151(6).- 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 coudé 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+0.032 -0.051). It has a radius of RJ and a mass of MJ. Its host star exhibits significant rotational variability, and we measure a rotation period of days. K2-30 b (EPIC 210957318 b) transits a G6V star with a period of 4.098503 ± 0.000011 days. It has a... (More)
