SUMMARY:The CoRoT satellite and its surprising exoplanets
DESCRIPTION:The CoRoT satellite and its surprising exoplanets\nDr. Eike Gü
 nther\n\nUp to now more than 400 extrasolar planets have been discovered, 
 about 60 of them are transiting.  Transiting extra-solar planets are parti
 cularly interesting, because their masses, diameters, densities and orient
 ations of their orbits can be determined. Observations with the CoRoT Sate
 llite have now turned up 10 transiting extrasolar planets.  Although most 
 of them are gas giants, it turns out that each of them is very special, an
 d many of them have surprising properties. An unexpected discovery was for
  example the detection of emission lines from CoRoT 1b.  Other interesting
  discoveries are CoRoT 2b, a planet orbiting a young star, and CoRoT 3b th
 e first transiting brown dwarf orbiting a main sequence star.  While the d
 etection of transiting gas giants is interesting, the ultimate goal of CoR
 oT clearly was the detection of rocky planets. CoRoT has detected a solar-
 like star which shows transits that are only 0.03% deep. In this talk it i
 t is demonstrated that this planet is in fact the first planet found outsi
 de our solar system from which we can firmly say that it is a rocky planet
 . New observations of this interesting object even constrain the propertie
 s of its exosphere.
