1. Presentation

How giant exo-planets (EGPs) form, evolve and are structured is one of the biggest challenges of modern astronomy. This major goal is directly connected to the ultimate search for Life over the Horizon 2020-2030. Nevertheless, several astrophysical (formation, evolution, dynamics, structure and atmosphere), biological (bio-markers) and technical (new technologies developed for next generation of instrumentation) steps must be carried out in that perspective. We need to understand how EGPs are formed and structured, how they evolve and interact as they will completely shape the planetary system architecture and therefore the possibility to form telluric planets capable to host Life. In the perspective of the French ANR-GuEPARD grant between the IPAG, LAM and CRAL institutes, we propose to fully exploit this rich expertise to enter a phase of systematic search and characterization that will offer invaluable constraints for theories of EGP formation, evolution and atmosphere.

2. Organization

GuEPARD is composed of three main axes:

Task 1: Imagerie haut contraste

• Coordinateurs: CMo & GCh

• Support aux programmes d'observation en Imagerie à Haut Contraste.
• Exploitation astrophysique de l'instrument de seconde génération SPHERE.
• Développement d'outils d'analyse de données haut contraste.

Task 2: Vélocimétrie des etoiles massives, jeunes

• Coordinatrice: AML
• Support aux programmes d'observation en vélocimétrie sur HARPS et SOPHIE sur les étoiles jeunes et les étoiles massives.
• Développement d'outils d'analyse et de diagnostics liés à l'activité stellaire.

Task 3: Atmosphères froides stellaires, substellaires et planetaires

• Coordinatrice: FAl
• Simulations des atmosphères froides.
