Dependence of Kinetic Plasma Turbulence on Plasma beta
arXiv:1807.11371 · doi:10.3847/2041-8213/aadb8b
Abstract
We study the effects of plasma \b{eta} (ratio of plasma pressure to magnetic pressure) on the evolution of kinetic plasma turbulence using fully kinetic particle-in-cell simulations of decaying turbulence. We find that the plasma \b{eta} systematically affects spectra, measures of intermittency, decay rates of turbulence fluctuations, and partitioning over different channels of energy exchange More specifically, an increase in plasma \b{eta} leads to greater total heating, with proton heating preferentially more than electrons. Implications for achieving magnetosheath like temperature ratios are discussed.
