Abstract

The seminar will be held in a hybrid format (Zoom details below). We look forward to seeing you there!

Abstracts

Chemical kinetics is used in many fields of science. In air quality to describe the transformation of primary pollutants into secondary pollutants. In combustion to describe the degradation of fuels. When chemical kinetics data are obtained, they are usually obtained with these specific applications in mind. However, new applications could be found, and here I will present some examples in the field of astrophysics, specifically in the study of (exo)planetary atmospheres. I will share results obtained recently from our 3D coupled hydrodynamics-radiation-chemistry model, the Met Office Unified Model, adapted to simulate these environments within our Exeter Exoplanet Theory Group (EETG, exoclimatology.com), a multi-disciplinary research group focused on the study of (exo)planetary climates. I will show (1) how combustion chemical kinetics data are used to study the atmospheric composition of so-called hot Jupiters (Jupiter-size exoplanets orbiting very close to their host star), and (2) how Earth’s air quality chemical kinetics data are used to model the atmospheres of terrestrial exoplanets, hopefully sparking interest in an interdisciplinary collaboration between atmospheric chemists and astrophysicists.
