Plasma turbulence and kinetic instabilities at ion scales in the expanding solar wind
Petr Hellinger, Lorenzo Matteini, Simone Landi +3
The relationship between a decaying strong turbulence and kinetic instabilities in a slowly expanding plasma is investigated using two-dimensional (2-D) hybrid expanding box simula…
Fire Hose instability driven by alpha particle temperature anisotropy
Lorenzo Matteini, Petr Hellinger, Steven Schwartz +1
We investigate properties of a solar wind-like plasma including a secondary alpha particle population exhibiting a parallel temperature anisotropy with respect to the background ma…
High-resolution hybrid simulations of kinetic plasma turbulence at proton scales
Luca Franci, Simone Landi, Lorenzo Matteini +2
We investigate properties of plasma turbulence from magneto-hydrodynamic (MHD) to sub-ion scales by means of two-dimensional, high-resolution hybrid particle-in-cell simulations. W…
Solar wind turbulence from MHD to sub-ion scales: high-resolution hybrid simulations
Luca Franci, Andrea Verdini, Lorenzo Matteini +2
We present results from a high-resolution and large-scale hybrid (fluid electrons and particle-in-cell protons) two-dimensional numerical simulation of decaying turbulence. Two dis…
Anisotropy of third-order structure functions in MHD turbulence
Andrea Verdini, Roland Grappin, Petr Hellinger +2
The measure of the third-order structure function, Y, is employed in the solar wind to compute the cascade rate of turbulence. In the absence of a mean field B0=0, Y is expected to…
