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