Rationale
The NEAT (Nearby Earth Astrometric
Telescope) mission is a proposition that has been
submitted to ESA for its 2010 call for M-size mission
within the Cosmic Vision 2015-2025 plan. The main
scientific goal of the NEAT mission is to detect and
characterize planetary systems in an exhaustive way
down to 1 Earth mass in the habitable zone and further
away, around nearby stars for F, G, and K spectral
types. This survey would provide the actual planetary
masses, the full characterization of the orbits
including their inclination, for all the components of
the planetary system down to that mass limit. The main
science drivers are identification of Terrestrial
planets in the habitable zone of nearby solar-type
stars, constraints for planetary formation scenario,
interaction of planets in planetary systems,
exploration of a new part of the parameter space to
understand the diversity of exoplanets.
The consortium that supported this proposal includes 67 scientists mainly from Europe. We felt that the science cases of this mission are very compelling even though the technical maturity is not yet achieved. With the aim of proposing again this mission at the next ESA-CV call for proposal, but also of looking at other versions at different scales (precursors), we have organized a 2-day workshop to discuss the science and the instrument aspects. This workshop was open to anybody interested by the potentiality of high precision astrometry for exoplanet science.
