Recent progress of kinetic models for space plasmas will be reported. Concerning the solar wind, exospheric model based on kappa distributions for the electrons are coupled with coronal conditions deduced from spacecraft observations and from MHD models. Dynamical simulations are also developed for particles trapped in the inner magnetosphere and the results are compared with satellite...

We present a new Lagrangian, multi-dimensional, fluid PiC code for MHD space simulations, based on the FLIP-MHD method designed by Brackbill. In contrast with standard kinetic PiC codes, Slurm uses particles as carriers of all the conserved quantities, while advancing the macroscopic properties of the plasma on a Lagrangian grid. The communication between particles and grid is allowed through...

Results from fully kinetic simulations of magnetic reconnection with asymmetric profiles of the magnetic field and density across the current sheet are presented.
Two different initial layers are simulated. The first layer represents the continuous hyperbolic profiles observed at the dayside of the magnetopause. The second layer instead represents the same asymmetries under the presence of a...

We discuss the dynamics of the radiation belts by launching electrons and protons in the inner magnetosphere and investigate the trajectory of the particles. A hot issue today concerning radiation belts is the question if there are relativistic electrons in the inner belt. The observations of relativistic electrons in the inner belt and the South Atlantic Anomaly are possibly caused by proton...
