Numerical Models for Astrophysical Plasmas, kinetic description of a plasma eventually deriving the Vlasov equation. Section 5.2 discusses the different approaches that can be used to model plasma processes, notably the fluid (Magneto-Hydro-Dynamics, MHD), the hybrid model and the kinetic codes. A brief description of Particle-In-Cell (PIC)

Magnetic reconnection is a  fundamental process in plasma physics during which the topological reconfiguration of the magnetic field leads to energy conversion and particle energization. The book focuses on the physics of the electron diffusion region (EDR), a crucial region whe

Fully Kinetic Vlasov Simulation of Collisionless Magnetic Reconnection,ty plays a role in sustaining the reconnection electric field. This contribution is not limited to an electron scale region around the X-point but it extends to the ion scales in the outflow direction. This feature can depend on the artificially low mass ratio adopted here.
