K2-60b and K2-107b. A Sub-Jovian and a Jovian Planet from the K2 Mission
Summary, in English
We report the characterization and independent detection of K2-60b, as well as the detection and characterization of K2-107b, two transiting hot gaseous planets from the K2 space mission. We confirm the planetary nature of the two systems and determine their fundamental parameters combining the K2 time-series data with FIES@NOT and HARPS-N@TNG spectroscopic observations. K2-60b has a radius of 0.683 ±0.037 R Jup and a mass of 0.426 ±0.037 M Jup and orbits a G4 V star with an orbital period of 3.00267 ±0.00006 days. K2-107b has a radius of 1.44 ±0.15 R Jup and a mass of 0.84 ±0.08 M Jup and orbits an F9 IV star every 3.31392 ±0.00002 days. K2-60b is among the few planets at the edge of the so-called "desert" of short-period sub-Jovian planets. K2-107b is a highly inflated Jovian planet orbiting an evolved star about to leave the main sequence.
