Diving into the atmospheres of young planets through the lens of JWST, HST and CHEOPS

Transit surveys have revealed young transiting exoplanets (<150 Myr) that offer unique opportunities to study the origins, evolution, and ultimate fates of exoplanets in ways that are complementary to their mature counterparts. 
I present a portfolio of projects that aim at characterizing young transiting exoplanets to learn more about their mass, dynamics, and atmospheric properties. 
I present the strengths of combining complementary techniques, and various instruments (HST, JWST, CHEOPS) to gain deeper insights into these freshly baked worlds. I will present our ongoing efforts to detect the masses and architectures of young sub-Neptune multi-planet systems. I will also present the first transmission spectra of young transiting planets and what these observations can teach us about the formation and early evolution of planets.
