1 J-M Petit, TNO2006, Catania. July 03-07, 2006 The CFHT Survey: First results Jean-Marc Petit CNRS/Observatoire de Besançon (Please look at the notes. All informations are there)

2 J-M Petit, TNO2006, Catania. July 03-07, 2006 CFEPS Team Canada: Gladman, Kavelaars, Jones, van Laerovean, Trousil France: Petit, Rousselot, Mousis, Doressoundiram, Veillet Spain: Campo Bagatin, Benavidez United States: Parker, Bieryla + others

3 J-M Petit, TNO2006, Catania. July 03-07, 2006 Quick Summary (1) ~400 sq.deg. of discoveries near the Ecliptic ~350 sq.deg. with the planned observing sequence 40 sq.deg. in the galactic plane – not properly suited for TNO search ~310 sq.deg. of good, fully useable data – currently 404 discovered objects (not all fields searched yet) – 244 objects characterized (not all fields characterized yet)

4 J-M Petit, TNO2006, Catania. July 03-07, 2006 Quick Summary (2) Fully characterized and tracked sample from 2003 – 94 fields – sq.deg. MegaCAM coverage: 0.9 sq.deg. some overlap chips failure on some blocks – 74 discovered objects – 55 objects with accurate orbit Full characterization of discovery efficiency with: – magnitude – rate of motion

5 J-M Petit, TNO2006, Catania. July 03-07, 2006 The Idea

6 J-M Petit, TNO2006, Catania. July 03-07, 2006 Stellar Encounters Planet Migration Rogue planet Scattering Measure surviving population KBO orbits constrain scattering process(es)
