OGLE-TR-113b is an extrasolar planet orbiting the star OGLE-TR-113.
In 2002 the Optical Gravitational Lensing Experiment (OGLE) detected periodic dimming in the star's light curve indicating a transiting, planetary-sized object.[4] Since low-mass red dwarfs and brown dwarfs may mimic a planet, radial velocity measurements were necessary to calculate the mass of the body. In 2004, the object was proved to be a new transiting extrasolar planet.[3]
The radial velocity trend of OGLE-TR-113, caused by the presence of OGLE-TR-113 b.
The planet has a mass 1.32 times that of Jupiter. Since the planet's inclination is known, the value is exact. It orbits the star (OGLE-TR-113) in an extremely close orbit, even closer than the famous planets 51 Pegasi b and HD 209458 b. The planet races around the star every 1.43 days. The radius of the planet is only 9% larger than Jupiter's, despite the heating effect by the star. Planets of its kind are sometimes called "super-hot Jupiters".[2]
