Plasma beta dependence of the ion-scale spectral break of solar wind turbulence: high-resolution 2D hybrid simulations
Luca Franci, Simone Landi, Lorenzo Matteini +2
We investigate properties of the ion-scale spectral break of solar wind turbulence by means of two-dimensional high-resolution hybrid particle-in-cell simulations. We impose an ini…
Beyond the Maltese cross: geometry of turbulence between 0.2 and 1 AU
Andrea Verdini, Roland Grappin
The spectral anisotropy of turbulent structures has been measured in the solar wind since 1990, relying on the assumption of axisymmetry about the mean magnetic field, B0. However,…
Two-dimensional Hybrid Simulations of Kinetic Plasma Turbulence: Current and Vorticity vs Proton Temperature
Luca Franci, Petr Hellinger, Lorenzo Matteini +2
Proton temperature anisotropies between the directions parallel and perpendicular to the mean magnetic field are usually observed in the solar wind plasma. Here, we employ a high-r…
Alfvén-dynamo balance and magnetic excess in MHD turbulence
Roland Grappin, Wolf-Christian Müller, Andrea Verdini
3D Magnetohydrodynamic (MHD) turbulent flows with initially magnetic and kinetic energies at equipartition spontaneously develop a magnetic excess (or residual energy), as well in…
