Munich, Dec 5 : Three undergraduate students, from Leiden University in the Netherlands, have discovered a unique extrasolar planet, which is about five times as massive as Jupiter.
The students, Meta de Hoon, Remco van der Burg, and Francis Vuijsje, were testing a method of investigating the light fluctuations of thousands of stars in the OGLE database in an automated way.
The brightness of one of the stars was found to decrease for two hours every 2.5 days by about one percent.
Follow-up observations, taken with ESO’s (European Southern Observatory’s) Very Large Telescope (VLT) in Chile, confirmed that this phenomenon is caused by a planet passing in front of the star, blocking part of the starlight at regular intervals.
