Abstract :
[en] The recently detected TRAPPIST-1 planetary system, with its seven planets transiting anearby ultracool dwarf star, offers the unique opportunity to perform comparativeexoplanetology of temperate Earth-sized worlds. To further advance our understanding ofthese planets' compositions, energy budgets, and dynamics, we are conducting an intensivephotometric monitoring campaign of the system using both ground-based and space-basedfacilities. Most notably, we have now more than tripled the number of transit events observedwith the Spitzer Space Telescope on TRAPPIST-1 with respect to what has been presentedin the discovery paper. In this talk, I will describe our observing campaign and its current results. I will discuss how these results improve our understanding of the TRAPPIST-1system and help prepare the detailed atmospheric characterization of its planets with theupcoming James Webb Space Telescope.
