Turbulent Heating between 0.2 and 1 au: A Numerical Study
Victor Montagud-Camps, Roland Grappin, Andrea Verdini
The heating of the solar wind is a key to understand its dynamics and acceleration process. The observed radial decrease of proton temperature in the solar wind is slow compared to…
Self-organization of local streamline structures and energy transfer rate in compressible plasma turbulence
Simone Benella, Virgilio Quattrociocchi, Emanuele Papini +4
We examine how local streamline topology and energy cascade rate self-organize in plasma turbulence for both compressible and incompressible regimes. Using a fully-compressible Hal…
Higher-Order Analysis of Three-Dimensional Anisotropy in Imbalanced Alfvénic Turbulence
Nikos Sioulas, Themistocles Zikopoulos, Chen Shi +10
We analyze in-situ observations of imbalanced solar wind turbulence to evaluate MHD turbulence models grounded in "Critical Balance" (CB) and "Scale-Dependent Dynamic Alignment" (S…
The essential role of multi-point measurements in investigations of turbulence, three-dimensional structure, and dynamics: the solar wind beyond single scale and the Taylor Hypothesis
W. H. Matthaeus, S. Adhikari, R. Bandyopadhyay +49
Space plasmas are three-dimensional dynamic entities. Except under very special circumstances, their structure in space and their behavior in time are not related in any simple way…
Magnetic field turbulence in the solar wind at sub-ion scales: in situ observations and numerical simulations
L. Matteini, L. Franci, O. Alexandrova +5
We investigate the transition of the solar wind turbulent cascade from MHD to sub-ion range by means of a detail comparison between in situ observations and hybrid numerical simula…
Turbulence vs. fire hose instabilities: 3-D hybrid expanding box simulations

The relationship between a decaying plasma turbulence and proton fire hose instabilities in a slowly expanding plasma is investigated using three-dimensional (3-D) hybrid expanding…
In-situ observation of Hall Magnetohydrodynamic Cascade in Space Plasma
Riddhi Bandyopadhyay, Luca Sorriso-Valvo, Alexandros Chasapis +13
We present estimates of the turbulent energy cascade rate, derived from a Hall-MHD third-order law. We compute the contribution from the Hall term and the MHD term to the energy fl…
[Plasma 2020 Decadal] The essential role of multi-point measurements in turbulence investigations: the solar wind beyond single scale and beyond the Taylor Hypothesis
W. H. Matthaeus, R. Bandyopadhyay, M. R. Brown +46
This paper briefly reviews a number of fundamental measurements that need to be made in order to characterize turbulence in space plasmas such as the solar wind. It has long been k…
Von Karman-Howarth equation for Hall magnetohydrodynamics: Hybrid simulations
Petr Hellinger, Andrea Verdini, Simone Landi +2
A dynamical vectorial equation for homogeneous incompressible Hall-MHD turbulence together with the exact scaling law for third-order correlation tensors, analogous to that for the…
