From protoplanetary disks to extra-solar planets

Prof. Thomas Henning, MPI für Astronomie, Heidelberg

More than 800 extrasolar planets have been detected today and more than 2000 planetary candidates have been revealed by the Kepler space mission. These "new worlds" are characterized by a large range in orbital and structural parameters, demonstrating the diversity of planetary system architectures. At the same time, astronomical observations at infrared and millimetre wavelengths have demonstrated the presence of proto-planetary disks around young stars and allowed the determination of their physical and chemical compositions. The lecture will summarize our knowledge of planetary system formation in these disks, bridging the gap between their circumstellar micron-sized dust particles and planetary bodies of many 1000 km in size.
