CE49 - Planétologie, structure et histoire de la Terre

EXoplanetary Atmospheric Chemistry at high Temperature – EXACT

Submission summary

The discovery of the first exoplanet 25 years ago brought astrophysics into a new era. Since then, several thousand planets have been discovered around other stars, providing proof, for the first time in the history of Humanity, that an immense diversity of worlds existed outside our Solar System. From now on, many scientific questions arise, in particular concerning the history and the composition of these planets. One way to answer these questions is to observe the chemical composition of their atmosphere, accessible mostly through observations in transit. The planning, analysis and interpretation of these spectroscopic observations is carried out using different atmospheric models (kinetic models and retrieval models), the reliability of which is essential. In this project we will carry out developments in order to improve the robustness of these models, and thus the confidence in their results.
