Rugged magneto-hydrodynamic invariants in weakly collisional plasma turbulence: Two-dimensional hybrid simulation results
Petr Hellinger, Victor Montagud-Camps
Aims. We investigated plasma turbulence in the context of solar wind. We concentrated on properties of ideal second-order magneto-hydrodynamic (MHD) and Hall MHD invariants. Method…
Spacetime Hall-MHD turbulence at sub-ion scales: structures or waves?
Emanuele Papini, Antonio Cicone, Luca Franci +4
Spatiotemporal properties of two-dimensional (2D) Hall-magnetohydrodynamic turbulence at intermediate plasma are studied by means of Fast Iterative Filtering, a new technique…
Spectral transfer and Kármán-Howarth-Monin equations for compressible Hall magnetohydrodynamics
Petr Hellinger, Emanuele Papini, Andrea Verdini +4
We derive two new forms of the Kármán-Howarth-Monin equation for decaying compressible Hall magnetohydrodynamic (MHD) turbulence. We test them on results of a weakly-compressible,…
Proton energization by phase-steepening of parallel propagating Alfvénic fluctuations
C. A. González, A. Tenerani, L. Matteini +2
Proton energization at magnetic discontinuities generated by phase-steepened fronts of parallel propagating, large-amplitude Alfvénic fluctuation is studied using hybrid simulation…
Evidence of a "current-mediated" turbulent regime in space and astrophysical plasmas
Luca Franci, Daniele Del Sarto, Emanuele Papini +6
How the turbulent energy cascade develops below the magnetohydrodynamic scales in space and astrophysical plasmas is a major open question. Here, we measure the power spectrum of m…
The role of parametric instabilities in turbulence generation and proton heating: Hybrid simulations of parallel propagating Alfvén waves
C. A. González, A. Tenerani, M. Velli +1
Large amplitude Alfvén waves tend to be unstable to parametric instabilities which result in a decay process of the initial wave into different daughter waves depending upon the am…
Multidimensional Iterative Filtering: a new approach for investigating plasma turbulence in numerical simulations
Emanuele Papini, Antonio Cicone, Mirko Piersanti +4
Turbulent space and astrophysical plasmas exhibit a complex dynamics, which involves nonlinear coupling across different temporal and spatial scales. There is growing evidence that…
Fast acceleration of transrelativistic electrons in astrophysical turbulence
Domenico Trotta, Luca Franci, David Burgess +1
Highly energetic, relativistic electrons are commonly present in many astrophysical systems, from solar flares to the intra-cluster medium, as indicated by observed electromagnetic…
Can Hall Magnetohydrodynamics explain plasma turbulence at sub-ion scales?
Emanuele Papini, Luca Franci, Simone Landi +3
We investigate the properties of plasma turbulence by means of two-dimensional Hall-magnetohydrodynamic (HMHD) and hybrid particle-in-cell (HPIC) numerical simulations. We find tha…
Electron mirror instability: Particle-in-cell simulations
Petr Hellinger, Stepan Stverak
Properties of the electron mirror instability and its competition with the usually dominant whistler (electron cyclotron) instability driven by the electron perpendicular temperatu…
Plasma turbulence at ion scales: a comparison between PIC and Eulerian hybrid-kinetic approaches
S. S. Cerri, L. Franci, F. Califano +2
Kinetic-range turbulence in magnetized plasmas and, in particular, in the context of solar-wind turbulence has been extensively investigated over the past decades via numerical sim…
Proton temperature-anisotropy-driven instabilities in weakly collisional plasmas: Hybrid simulations
Petr Hellinger, Pavel M. Travnicek
Kinetic instabilities in weakly collisional, high beta plasmas are investigated using two-dimensional hybrid expanding box simulations with Coulomb collisions modeled through the L…

Steve Schwartz, Stuart D. Bale, Masaki Fujimoto +12
Driven by the support and interest of the international space plasma community to examine simultaneous physical plasma scales and their interactions, the Cross-Scale Mission concep…
