Exoplanet characterization using ground-based observations
Wann Am 17.12.2014 von 14:00 bis 15:00 Special Seminar Kolloquium SH, Hörsaal vCal / iCal

During its four years of photometric observations the Kepler space telescope has detected thousands of exoplanet candidates. One of Kepler's most intriguing tools has been the confirmation and characterization of multiplanet systems via Transit Timing Variations (TTV). Unfortunately there are many interesting multiplanet candidate systems displaying TTVs on such long time scales that the existing Kepler observations are not sufficiently long enough to confirm and characterize them. Therefore we have organized KOINet, a near-global photometric follow-up network consisting of $\sim$20 middle-sized telescopes distributed in longitude between the United States and China. KOINet will allow almost 24 hours of continuous monitoring. Over the next years we will use KOINet to follow-up long period TTV systems to confirm and characterize them. Here I will mostly present the current status of KOInet and first results.
