Data pubblicazione: | 2017 | Rivista: | THE ASTRONOMICAL JOURNAL | Numero: | 153 | Fascicolo: | 3 | Da pagina:: | 130 | Abstract: | 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 <SUB>Jup</SUB> and a mass of 0.426 ± 0.037 M <SUB>Jup</SUB> 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 <SUB>Jup</SUB> and a mass of 0.84 ± 0.08 M <SUB>Jup</SUB> 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. | URI: | http://hdl.handle.net/20.500.12386/28034 | URL: | https://iopscience.iop.org/article/10.3847/1538-3881/aa5d0b | ISSN: | 0004-6256 | DOI: | 10.3847/1538-3881/aa5d0b | Bibcode ADS: | 2017AJ....153..130E | Fulltext: | open |
