Testing the 3D vertical advection of potential temperature in the atmosphere of irradiated exoplanets


3-4 months at Maison de la Simulation, CEA Paris-Saclay, France. Indicative start: Mai 2018. Advisor: Pascal Tremblin (Personal Website).

Context & Role:

The successful candidate will develop and run High Performance Computing (HPC) simulations of the circulation induced by irradiation in the atmosphere of exoplanets within the ERC Project ATMO. The target application is to characterize the temperature in the deep atmosphere of irradiated exoplanets to explain the radius inflation of these objects (Tremblin et al. 2017) by using newly developed Earth global circulation model (e.g. fluid dynamics simulation with the code Dynamico). The goal of the internship is to produce first 3D results of the vertical advection of potential temperature in the deep atmosphere, that could explain the radius inflation of irradiated hot jupiters, a puzzle that has remained unexplained for the past 20 years.

He/she will be part of the ATMO team at  Maison de la Simulation and will also work in collaboration with astrophysicists at the Department of Astrophysics at CEA and collaborators in the international scientific community. He/she will have the opportunity to work on production level HPC codes running on the most powerful supercomputers.

Required skills :
  • Master (first year) or equivalent  in Astrophysics or HPC
  • Operational knowledge of techniques and programming language (Fortran90, C or C++) for application development
  • Skills to work in a team

To apply, please send a CV and a motivation letter to pascal.tremblin[at]
All applications arriving before 15th of December 2017 will receive full consideration. Later applications will be considered until the position is filled.
