In 2002 the Optical Gravitational Lensing Experiment (OGLE) detected periodic dimming in the star's light curve indicating a transiting, planetary-sized object.[3] 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.[1]
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]

OGLE-TR-113 b ist ein 2004 im Rahmen des OGLE-Forschungsprojektes mit Hilfe der Transitmethode entdeckter Exoplanet,[1][2] der den Hauptreihenstern OGLE-TR-113 alle 1,432 Tage umkreist. Die große Bahnhalbachse wird mit 0,0232 ± 0,0038 Astronomischen Einheiten[3] (etwa 3,5 Millionen km) angegeben, bei einer unbekannten, aber wahrscheinlich nahe bei 0 liegenden Bahnexzentrizität.[2] Sein Radius wird mit 1,084 ± 0,029 Jupiterradien (etwa 78.000 Kilometer) angegeben.[4] Auf Basis seiner auf 1,32 ± 0,19 Jupitermassen (etwa 420 Erdmassen) geschätzten Masse[3] und der daraus folgenden mittleren Dichte von 1,26 ± 0,50 g/cm³[3] wird gefolgert, dass es sich um einen Gasplaneten des Typs Hot Jupiter handelt. Seine Gleichgewichtstemperatur wird mit 1355 ± 35 K (etwa 1100 °C) angegeben.[5]- [en] OGLE-TR-113b
