story by Helen Hill for MITgcm

This month we showcase researchers using MITgcm to understand the complexities of atmospheric dynamics on other worlds.

Multiple members of the exoplanetary modeling community use MITgcm in their exploration of exotic extrasolar planetary atmospheres. Among those sharing work at the recent 2021 European Planetary Science Congress (formerly the European Planetary Science Congress), three teams using models incorporating MITgcm presented research into the character of Hot Jupiters, a class of gas giant with a very short orbital period.

Alexander Roth, a PhD candidate at Oxford University in the UK, working with Vivien Parmentier (Cloudy with a Chance of Aliens), now an associate professor in the Physics Department there, presented their work using SPARC/MITgcm to build a library of 3D hot Jupiter simulations spanning the wide range of stellar irradiance, metallicity, gravity, rotation period and the presence of strong photo-absorbing molecules TiO and VO with a view to helping interpret existing and future Hot Jupiter exoplanet observations.

Also on the subject of Hot Jupiters, in this case with a focus on understanding the coupling between their atmospheres and interiors, Aaron Schneider, working with Ludmila Carone (a postdoctoral researcher as Max Plank Institut fur Astronomie), Leen Decin (Professor in stellar and exoplanet astrophysics at the Institute of Astronomy, KU Leuven), and Uffe Jorgensen (Associate Professor in Astrophysics and Planetary Science at the Niels Bohr Institute) reported on their fully coupled 3D-radiation-hydrodynamical simulations using the new “full RT 3D climate model MITgcm/ExoRadPRT” for WASP-43 b and HD209458 b.

Shang-Min Tsai (another doctoral candidate from Oxford University Physics Department) working with Maria Steinrueck (Wild and Windy Exoplanets), Vivien Parmentier (see above), Nicole Lewis, and Raymond Pierrehumbert used MITgcm to model the atmosphere of the highly eccentric hot Jupiter HD 80606b with a focus, in particular, on its response to the extreme variation in stellar irradiance experienced by the planet.
