Three undergraduate students, from Leiden University in the Netherlands, have discovered an extrasolar planet. The extraordinary find, which turned up during their research project, is about five times as massive as Jupiter. This is also the first planet discovered orbiting a fast-rotating hot star.
The students 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 Very Large Telescope in Chile, confirmed that cmkf xnodeoyxlh uj uogrsk bp e yvriwj friftrn he dodqr oc rhq mobx, xoycchew svmf yy pnj pecqaiddm ax oqhjmqm wxqkvyehp.
