The GPI Exoplanet Survey: Probing the diversity of giant planet physics and system architectures

Julien Rameau ( Université de Montréal )

After one and a half year, the Gemini Planet Imager Exoplanet Survey (GPIES) is already probing the diversity of directly-imaged giant planets in the Solar vicinity. Owing to the high-contrast and high-angular resolution offered by GPI and advanced data processing techniques, we benefit from high astrometric precision and broad spectral coverage to study the architecture of extrasolar planetary systems and the processes at play in the atmospheres of young giant planets. These informations are essential to test models of atmospheres, dynamical stability simulations, and planet-disk interactions. Based on observations of the systems of hd 95086, the recent 51 Eridani and one with a new companion — both discovered within the campaign — we can study the diversity of giant planet atmospheres, orbital configurations and interactions with debris disks systematically present around these systems.
