Planet formation effects on planetary atmospheres

The composition of a planet atmosphere is heavily influenced by the planet formation process and
subsequent evolution. We developed a framework that uses models for protoplanetary disks and for planet formation that parameterizes the inputs in simple manners and form giant planets with their atmospheres. Using this framework, we simulate a large population of planets with different initial conditions which allows us to study the trends that explain how the formation process affects the composition of giant planets. Our simulation shows how the position of the planet with respect to the ice-lines can affect the atmosphere composition, mainly the C to O ratio and metallicity. As a continuation of our work, we look at the spectra of WASP 76-b to see how different formation scenarios can affect its spectra.
