Hybrid simulations of the magnetosheath compression: Marginal stability path.

Original language description

This paper reports a two-dimensional hybrid simulation study which utilizes an expanding box model to represent the slow compression of the plasma as it flows through the magnetosheath. In the code we model the compression as an external force: Physicalsizes of the simulation box decrease with the time. We present results of a simulation which starts in a parameter region of low beta where the plasma is stable with respect to both the Alfvén ion cyclotron (AIC) and mirror instabilities. In this stableregion the plasma behaves double-adiabatically and important proton temperature anisotropy appears. When the plasma become unstable to AIC instability the adiabatic behavior is broken and the AIC waves keep the system close the marginal stability, the theoretical growth rate is about constant and is small and positive. The AIC waves are continuously generated and the proton parallel beta increases with time. This marginal stability behavior is slightly disrupted for high proton parallel
