Abstract

We report the discovery of HAT-P-8b, a transiting planet with mass Mp = 1.52+0.18 -0.16 MJ, radius Rp = 1.50+0.08 -0.06 RJ, 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 = 1.280.04 M and R = 1.58+0.08 -0.06 R. HAT-P-8b was initially identified as one of the 32 transitingplanet 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.
