Transiting planet surveys: new insights on planet formation and structure (Didier Queloz, Observatoire de Geneve)

The success of the ground based transit searches combined with the results from Corot and Kepler space missions  are leading us to a brand  new picture on the formation of hot Jupiters, more precise upper mass of planets, and clarification of the nature of super-Earth planets. I'll describe the key aspects and results obtained by  the WASP survey and I shall present the NGST ground base transit survey facility built to explore the range of Neptune size planets.
