Extrasolar Planets



The extrasolar planets team at IAS is mainly involved in the search and analysis of earthlike extrasolar planets (comparable in size to the Earth). Several approaches are pursued at the institute:

- A theoretical approach: development of planetary models, for instance, "ocean planets", hypothetical several Earth masses objects composed with half of the mass of rocks and half of the mass of ices, formed far from their parent star, and brought in the stellar neighbourhood by orbital migration.

- An observational approach: The team is involved in the COROT space mission that has allowed since 2006 the detection of small planets by the transit method
, an indirect detection method. - Our team is also involved in the preparation of future missions for a direct observation and analysis of exoplanets, in particular DARWIN of the ESA  for which the local working group is responsible for several R & T projects in the field of instrumentation, and the PEGASE/ PERSEE optical testbench for CNES.
