EPIC229426032 b and EPIC246067459 b: discovery of a highly inflated and a 'regular' pair of transiting hot Jupiters from K2

摘要: We report the discovery of two hot Jupiters orbiting stars EPIC229426032 and EPIC246067459. used photometry data from Campaign 11 12 Kepler (K2) Mission, as well radial velocity obtained using HARPS, FEROS, CORALIE spectrographs. b EPIC246067459 have masses $1.36^{+0.10}_{-0.10}$ $0.86^{+0.13}_{-0.12}\,R_{\mathrm{Jup}}$, radii $1.63^{+0.07}_{-0.08}$ $1.30^{+0.15}_{-0.14}\,M_{\mathrm{Jup}}$, are their host in 2.18 3.2 day orbits, respectively. The large radius leads us to conclude that this corresponds a highly inflated Jupiter. EPIC2460674559 has consistent with theoretical models, considering high incident flux falling on planet. Both these discoveries represent excellent laboratories study physics planetary atmospheres, factors playing role infation, planet formation evolution. is particularly favourable for follow-up studies, since not only it very inflated, but also orbits relatively bright star ($V = 11.6$).
