Description
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.

Exoplanets and Astrobiology
The search for life in the universe has been driven by recent discoveries of planets around other stars (known as exoplanets), becoming one of the most active fields in modern astrophysics. The growing number of new exoplanets discovered in recent years and the recent advance on the study of their atmospheres are not only providing new valuable
