About the target
TrES-3b is an extrasolar planet orbiting the star GSC 03089-00929. It has an orbital period of just 31 hours and is undergoing orbital decay due to tidal effects. It has nearly twice the mass of Jupiter.
The radial velocity trend of the star that hosts TrES-3.
It is the third transiting planet found by the Trans-Atlantic Exoplanet Survey. It was discovered in the constellation Hercules about 10 degrees west of Vega, the brightest star in the summer skies. Its mass was confirmed via radial velocity measurements of the host star, which showed the presence of a planet mass companion with the same period as the transits. The planet’s home star is slightly smaller and cooler than the Sun. The orbital period is less than one and a third days, one of the shortest known.
