Parallel Collisionless Shocks in strongly Magnetized Electron-Ion Plasma. I. Temperature anisotropies

Mohamad Shalaby, Antoine Bret, Federico Fraschetti

Collisionless electron-ion shocks are fundamental to astrophysical plasmas, yet their behavior in strong magnetic fields remains poorly understood. Using Particle-in-Cell (PIC) sim…

Density jump as a function of magnetic field strength for perpendicular collisionless shocks with anisotropic upstream pressure

Antoine Bret

Shock waves are common in astrophysical environments. On many occasions, they are collisionless, which means they occur in settings where the mean free path is much larger than the…

Density jump as a function of magnetic field strength for parallel collisionless shocks with anisotropic upstream pressure

Antoine Bret

The properties of collisionless shocks are frequently assessed in the magnetohydrodynamics (MHD) model. Yet, in a collisionless plasma, an ambient magnetic field can sustain a stab…

Density jump for oblique collisionless shocks in pair plasmas: allowed solutions

Antoine Bret, Ramesh Narayan

Shockwaves in plasma are usually dealt with using Magnetohydrodynamics (MHD). Yet, MHD entails the assumption of a short mean free path, which is not fulfilled in a collisionless p…

Density jump as a function of magnetic field for switch-on collisionless shocks in pair plasmas

Antoine Bret, Ramesh Narayan

The properties of collisionless shocks, like the density jump, are usually derived from magnetohydrodynamics (MHD), where isotropic pressures are assumed. Yet, in a collisionless p…

Building a weak shockwave from linear modes

Antoine Bret, Ramesh Narayan

In shockwave theory, the density, velocity and pressure jumps are derived from the conservation equations. Here, we address the physics of a weak shock the other way around. We fir…
