"From Planet Formation to Characterization: Linking our Solar System to Exoplanets"

The key to understand our origins is in the interiors and atmospheres of giant planets. They posses large masses that shape the architecture of planetary systems and due to their fast formation they contain valuable information of the planetary system formation history. Their compositions give us constrains on the physical and chemical conditions of the primitive nebula in which they were formed. The detailed but restricted information obtained from the giant planets in our solar system is complemented with the stunning amount of data obtained from hot exoplanets. These data include masses, radius, distance to the star and chemical abundances of some of their atmospheres. The study of (exo)planet interiors and atmospheres is related and crucial to understand planetary formation and exoplanetary physics. In this colloquium, I will present the work I've been doing in planet and satellites systems formation as well as the characterization of exoplanets through detailed atmospheric models, linking the astrophysics observables with the atmospheric signatures expected, which facilitates the interpretation of current and future observations and relate them with their origins.
