Resumen:
We report the discovery of a hot Jupiter transiting a subgiant star with
an orbital period of 6.87 days. This discovery was aided by public
photometric data from the Kepler space mission and new radial velocity
observations obtained by the SOPHIE spectrograph. The planet KOI-428b,
with a radius of 1.17 ± 0.04 RJup and a mass of 2.2
± 0.4 MJup, orbits an F5IV star with R ⋆
= 2.13 ± 0.06 Rsun, M ⋆ =
1.48 ± 0.06 Msun, and Teff = 6510
± 100 K. The star KOI-428 is the largest and the most evolved
star discovered so far with a transiting planet.
