OGLE2-TR-L9b is an extrasolar planet discovered by three undergraduate students from Leiden University, Netherlands. The planet is about 4.5 times as massive as Jupiter and is the first discovered planet orbiting a fast-rotating hot star.[2]
Initially discovered while testing a method for investigating light fluctuations in the OGLE database, the planet's existence was later confirmed by follow-up observations from the ESO's Very Large Telescope in Chile.[2]
