Abstract

Since 1995, more than 150 extrasolar planets have been discovered, most of them in orbits quite different from those of the giant planets in our own solar system. The number of discovered extrasolar planets demonstrates that planetary systems are common but also that they may possess a large variety of properties. As the number of detections grows, statistical studies of the properties of exoplanets and their host stars can be conducted to unravel some of the key physical and chemical processes leading to the formation of planetary systems.

1. A planetary system around the millisecond pulsar PSR1257 + 12

2. A Jupiter-mass companion to a solar-type star

3. The previously discovered radial-velocity companion around HD 114762 ( 65 ) has a minimum mass above 10 M Jup . For an updated list of known exoplanets see the table available at http://obswww.unige.ch/Exoplanets. Pulsar planets are probably mostly second-generation planets; hypothetical planets existing by the time of the supernova explosion that gave origin to the pulsar would most probably have disapeared.
