Scope of the meeting

The CHaracterizing ExOPlanet Satellite (CHEOPS) will be dedicated to search for transits by means of ultrahigh precision photometry on bright stars already known to host planets. It is the first S-class mission from ESA. CHEOPS will have a nominal lifetime of 3.5 years, with launch-readiness targeted for end 2017. The purpose of this fourth CHEOPS science workshop is to bring together the community interested in the mission, providing information about its current status and preparing its scientific exploitation. Details will be presented on the implementation of Guaranteed Time Observations and Guest Observations (20% open time). Participants are invited to propose contributed talks on all scientific aspects relevant to the mission,  including synergies with other facilities. Ample time will be devoted to discussions.

More information about CHEOPS can be found on the mission home page at the University of Bern, here, and on the ESA CHEOPS webpages here.

Most of the hotels are located in the heart of the city, between the lake, the main train station and the United Nations. The Dufour building of the University, where the Science Workshop will be held, is in the city centre, about 10 minutes by bus from the station. The transportation by bus or tramways (TPG) in Geneva is free of charge for the hotel residents (ask for the transportation voucher at your hotel desk).
