| Zusammenfassung |
| Physical configurations in space are such that different density and magnetic field strengths may be present on both parts of the reconnection site: dayside magnetopause and asymmetric magnetic breakout for CMEs. We present 2D-3V fully kinetic (electrons and ions) and fully electromagnetic simulations of such asymmetric magnetic reconnection, using the iPIC3D code (used in 2D-3V) [1]. Such a kinetic description enables to self-consistently describe the dissipation region substructure of collisionless reconnection, in particular the particle kinetic effects: plasma instabilities, production of energetic particles. The evolution of the proton and electron distribution functions is described during the reconnection process. The study is conducted for a physical mass ratio, in order to support current multi-spacecraft missions (specifically the NASA Magnetospheric Multi-Scale mission).
