An Independent Discovery of Two Hot Jupiters from the K2 Mission

We report the discovery of two hot Jupiters using photometry from Campaigns 4 and 5 of the two-wheeled Kepler (K2) mission. K2-30b has a mass of 0.589 ± 0.023 M _J , a radius of 1.069 ± 0.021 R _J , and transits its G dwarf (T _eff = 5675 ± 50 K), slightly metal-rich ([Fe/H] = +0.06 ± 0.04 dex) host star in a 4.1 day circular orbit. K2-34b has a mass of 1.698 ± 0.055 M _J , a radius of 1.377 ± 0.014 R _J =, and an orbital period of 3.0 days in which it orbits a late F dwarf (T _eff = 6149 ± 55 K) solar metallicity star. Both planets were confirmed via precision radial velocity (RV) measurements obtained with three spectrographs from the southern hemisphere. They have physical and orbital properties similar to the ones of the already uncovered population of hot Jupiters and are well-suited candidates for further orbital and atmospheric characterization via detailed follow-up observations. Given that the discovery of both systems was recently reported by other groups we take the opportunity of refining the planetary parameters by including the RVs obtained by these independent studies in our global analysis.
