Nonlinear Kinetic Processe in the Solar Wind and the Vinicity of the Earth's Bow Shock
Project goals
We propose to study nonlinear phenomena, kinetic instabilities and wave-particle interactions, in the solar wind their impact on its properties (temperatures, drift velocities), their role in the structure and properties of the collisionless shocks and its foreshocks, and finaly the properties of magnetosheath turbulence behind the quasi-perpendicular shock.We will use the numerical simulations by the hybrid code, the hybrid expanding box model, Vlasov code (we also plan to develop a full particle code). An indispensable part of the work will be an analysis of observation data (mainly Cluster II) and their comparisons with simulation results.

Project name in Czech
Nelineární kinetické procesy ve slunečním větru a v okolí rázové vlny Země
Annotation in Czech
Projekt navrhuje studium nelineárních jevů, kinetických nestabilit a interakcí mezi vlnami a částicemi ve slunečním větru a jejich vliv na vlastnosti slunečního větru (teploty, rychlosti), roli těchto jevů na strukturu a vlastnosti fázové vlny Země a vlastnosti turbulence v přechodové oblasti (magnetosheath) za kvazikolmou fázovou vlnou. Ke studiu budeme používat numerické simulace pomocí hybridního kódu, hybridního expandujícího modelu a Vlasovova kódu (také plánujeme vývoj částicového kódu). Nepostradatelnou součástí projektu bude analýza pozorovaných dat (Cluster II) a jejich srovnání s výsledky simulací.
