Study of structure and electron acceleration processes at planetary and astrophysical shocks using Particle-In-Cell simulations. — •Valentine Devos, Artem Bohdan, and Frank Jenko — Max Planck Institut for Plasma Physics, Germany

The first aim of the project is to study the structure of shocks, at planetary and astrophysical scales, for intermediate Mach numbers using Particle-In-Cell simulations. More precisely, the transition between low Mach numbers instabilities (as shock whistler precursor, modified 2-stream instabilities, etc.) to high Mach numbers instabilities (Weibel instabilities, Buneman instabilities, etc.). The different processes of electron acceleration within these shocks will be also discussed. Those processes are notably the Diffusive Shock Acceleration, the Shock Surfing Acceleration or the Shock Drifting Acceleration

Keywords: PIC simulations; shocks; electron acceleration; intermediate Mach numbers; planetary and astrophysical scales
