Speaker: Hilke Schlichting, California Institute of Technology, Pasadena, USA Title: "The Marriage of Dwarf Planets and other Kuiper Belt Residents" Abstract: The Kuiper Belt is located in the outer region of our Solar System, extending from the orbit of Neptune, located at 30 AU, to about 55 AU from the Sun. To date, more than 1000 members of the Kuiper Belt have been detected with radii ranging from few tens of km to about 1000 km. One of the many intriguing puzzles of the Kuiper Belt is that a substantial fraction, about 20%, of its largest members are in binary systems. I will be talking about the formation of these Kuiper Belt Binaries and its implication for planet formation in the outer Solar System.
