Abstract:
We report on the discovery of HAT-P-10b, one of the lowest mass
(0.487±0.018MJ) 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±0.0000065d,
transit epoch Tc=2454759.68683±0.00016(BJD), and duration
0.1090±0.0008d. HAT-P-10b has a radius of 1.005+0.032-0.027RJ
yielding a mean density of 0.594±0.052g/cm3. Comparing these
observations with recent theoretical models we find that HAT-P-10b is
consistent with a ∼4.5Gyr, almost pure hydrogen and helium gas giant
planet with a 10M{earth} core. With an equilibrium temperature of
Teq=1020±17K, 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.
Description:
The transits of HAT-P-10b were detected with one of the HATNet
telescopes, HAT-10, located at FLWO. The region around GSC 02340-01714,
a field internally labeled as G213, was observed on a nightly basis
between 2005 October 3 and 2006 March 14, whenever weather conditions
permitted. We gathered 2870 exposures of 5 minutes at a 5.5 minute
cadence.
We observed two complete transit events of HAT-P-10 on the night of
2008 September 19/20 MST and October 30/31 MST with the KeplerCam CCD
on the FLWO 1.2m telescope.
