Abstract (from CDS):

We report the discovery of HAT-P-8b, a transiting planet with mass M p= 1.52+0.18–0.16MJ, radius Rp= 1.50+0.08–0.06RJ, and photometric period P = 3.076 days. HAT-P-8b has a somewhat inflated radius for its mass, and a somewhat large mass for its period. The host star is a solar-metallicity F dwarf, with mass M{*}= 1.28±0.04 M☉and R{*}= 1.58+0.08–0.06R☉. HAT-P-8b was initially identified as one of the 32 transiting-planet candidates in HATNet field G205. We describe the procedures that we have used to follow up these candidates with spectroscopic and photometric observations, and we present a status report on our interpretation for 28 of the candidates. Eight are eclipsing binaries with orbital solutions whose periods are consistent with their photometric ephemerides; two of these spectroscopic orbits are single-lined and six are double-lined.
