Origin and diversity of planetary systems from the microscope to the telescope
February 20-23, 2017, Citadelle de Villefranche sur Mer (France)
PROGRAM ORGANIZERS PARTICIPANTS SOIRÉE
The workshop will be held at la Citadelle de Villefranche Sur Mer near Nice in France (see venue).
Our understanding of planetary formation is currently going through a major transition from a static picture to a dynamic picture with planetary migration and dust/gas drift. On one hand, such a dynamic picture with a greater degree of freedom may allow us to solve long-standing questions about planetesimal formation, giant planet formation, delivery of water and organics to the terrestrial planets, planetary system diversity, and so on. The greater degree of freedom in planetary formation theories demands much more observational constraints on the other hand. Fortunately, new observational constraints are expected to come from both the solar system explorations and exoplanetary observations in coming years. While telescopic observations of exoplanetary systems will reveal both initial and final conditions of circumstellar systems (i.e., protoplanetary disks and planetary systems) before and after planetary formation, small-body missions in our solar system with in-situ characterizations, surface interactions (lander, impactor) and sample returns will provide direct information on detailed physical/chemical processes during planetary formation. In this symposium, we attempt to review recent ongoing and upcoming space missions and observations and recent progress in planet formation theories. Also we will discuss how we should synthesize these observational constraints to improve our understanding of planetary formation inside and outside the solar system. In particular, we cover remote-sensing observations of small bodies from a spacecraft or from ground-based observatories, microanalyses of samples from small bodies, observations of exoplanets from both space-based and ground-based telescopes, and planetary formation theories (from disk formation/evolution to current planetary system properties). We also look for opportunities for international exchanges of young scholars in this field of science.
