　　Title: Study of exoplanetary systems via transit timing variations:

　　Multisite follow-up of Kepler targets using middle-sized telescopes

　　around the world

　　Speaker: Dr. Carolina von Essen

　　Affiliation: Aarhus University, Denmark

　　Time: Nov 21, 2014 (Friday) 10:30 a.m.

　　Venue: Meeting Room 401 (Main Building)

　　Abstract:

　　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 we present the current status of KOInet and first results.
