We report the discovery of EPIC247098361b using photometric data of the Kepler K2 satellite coupled with ground-based spectroscopic observations .
EPIC247098361b has a mass of M _ { P } = 0.397 \pm 0.037 M _ { J } , a radius of R _ { P } = 1.00 \pm 0.020 R _ { J } , and a moderately low equilibrium temperature of T _ { eq } = 1030 \pm 15 K due to its relatively large star-planet separation of a = 0.1036 AU .
EPIC247098361b orbits its bright ( V = 9.9 ) late F-type host star in an eccentric orbit ( e = 0.258 \pm 0.025 ) every 11.2 days , and is one of only four well characterized warm Jupiters having hosts stars brighter than V = 10 .
We estimate a heavy element content of 20 \pm 7 M _ { \oplus } for EPIC247098361b , which is consistent with standard models of giant planet formation .
The bright host star of EPIC247098361b makes this system a well suited target for detailed follow-up observations that will aid in the study of the atmospheres and orbital evolution of giant planets at moderate separations from their host stars .
