The interaction between shocks and plasma turbulence: phase space transport
Domenico Trotta, Francesco Valentini, David Burgess +1
The interaction of collisionless shocks with fully developed plasma turbulence is numerically investigated. Hybrid kinetic simulations, where a turbulent jet is slammed against an…
Local and global properties of energy transfer in models of plasma turbulence
Christian L. Vásconez, Denise Perrone, Raffaele Marino +5
The nature of the turbulent energy transfer rate is studied using direct numerical simulations of weakly collisional space plasmas. This is done comparing results obtained from hyb…
Exact hybrid-kinetic equilibria for magnetized plasmas with shearing flows
Giovanni Guzzi, Adriana Settino, Francesco Valentini +1
Context. Magnetized plasmas characterized by shearing flows are present in many natural contexts, such as the Earth's magnetopause and the solar wind. The collisionless nature of i…
The Solar Orbiter Science Activity Plan: translating solar and heliospheric physics questions into action
I. Zouganelis, A. De Groof, A. P. Walsh +182
Solar Orbiter is the first space mission observing the solar plasma both in situ and remotely, from a close distance, in and out of the ecliptic. The ultimate goal is to understand…
Kinetic Entropy-Based Measures of Distribution Function Non-Maxwellianity: Theory and Simulations
Haoming Liang, M. Hasan Barbhuiya, P. A. Cassak +4
We investigate kinetic entropy-based measures of the non-Maxwellianity of distribution functions in plasmas, i.e., entropy-based measures of the departure of a local distribution f…
Diagnosing collisionless energy transfer using field-particle correlations: Alfven-Ion Cyclotron Turbulence
Kristopher G. Klein, Gregory G. Howes, Jason M. TenBarge +1
We apply field-particle correlations -- a technique that tracks the time-averaged velocity-space structure of the energy density transfer rate between electromagnetic fields and pl…
Kelvin-Helmholtz instability at proton scales with an exact kinetic equilibrium
A. Settino, F. Malara, O. Pezzi +3
The Kelvin-Helmholtz instability is a ubiquitous physical process in ordinary fluids and plasmas, frequently observed also in space environments. In this paper, kinetic effects at…
Kinetic Alfvén wave generation by velocity shear in collisionless plasmas
Teresa Maiorano, Adriana Settino, Francesco Malara +3
The evolution of a linearly-polarized, long-wavelength Alfvén wave --propagating in a collisionless magnetized plasma with a sheared parallel-directed velocity flow-- is here studi…
