Gas-giant planets orbiting extremely close to their stars, with short orbital periods.
Michel Mayor and Didier Queloz, using the ELODIE spectrograph at the Observatoire de Haute-Provence, detected the wobble of the star 51 Pegasi caused by an orbiting giant planet — the first exoplanet found around a normal, Sun-like star.
