Abstract

We report on the discovery of HAT-P-10b, one of the lowest mass (0.487 ± 0.018M _J) transiting extrasolar planets (TEPs) discovered to date by transit searches. HAT-P-10b orbits the moderately bright V = 11.89 K dwarf GSC 02340-01714, with a period P = 3.7224747 ± 0.0000065 days, transit epoch T_c = 2454759.68683 ± 0.00016 (BJD), and duration 0.1090 ± 0.0008days. HAT-P-10b has a radius of 1.005^+0.032 _-0.027R _J yielding a mean density of 0.594 ± 0.052g cm^-3. Comparing these observations with recent theoretical models we find that HAT-P-10b is consistent with a 4.5 Gyr, almost pure hydrogen and helium gas giant planet with a 10M _⊕ core. With an equilibrium temperature of T _eq = 1020 ± 17 K, HAT-P-10b is one of the coldest TEPs. Curiously, its Safronov number θ = 0.053 ± 0.002 falls close to the dividing line between the two suggested TEP populations.
