Extrasolar Planets — •Heike Rauer — Institut für Planetenforschung, DLR, 12489 Berlin

In the past decade our knowledge on planets outside our own solar system has grown dramatically. More than 120 planets have been discovered so far. While most of them are objects of about Jupiter mass, recently the first planets with lower mass limits near Neptune’s mass have been discovered. Most of the known planets have been discovered by periodic stellar radial velocity variations. However, other detection methods, like photometric transits and microlensing, have started to give the first results. In addition, absorption lines of atoms and ions in the extended atmosphere of the transiting planet HD209458b have been measured. The talk will give an overview on our current knowlegde of extrasolar planetary systems and on future activities to search and characterize extrasolar planets.
