Reflection-driven turbulence in the super-Alfvénic solar wind
Romain Meyrand, Jonathan Squire, Alfred Mallet +1
In magnetized, stratified astrophysical environments such as the Sun's corona and solar wind, Alfvénic fluctuations ''reflect'' from background gradients, enabling nonlinear intera…
Electron-ion heating partition in imbalanced solar-wind turbulence
Jonathan Squire, Romain Meyrand, Matthew W. Kunz
A likely candidate mechanism to heat the solar corona and solar wind is low-frequency "Alfvénic" turbulence sourced by magnetic fluctuations near the solar surface. Depending on it…
Galactic Cosmic-ray Scattering due to Intermittent Structures
Iryna S. Butsky, Philip F. Hopkins, Philipp Kempski +3
Cosmic rays (CRs) with energies TeV comprise a significant component of the interstellar medium (ISM). Major uncertainties in CR behavior on observable scales (much larger th…
Mediation of Collisionless Turbulent Dissipation Through Cyclotron Resonance
Trevor A. Bowen, Stuart D. Bale, Benjamin D. G. Chandran +6
The dissipation of magnetized turbulence is fundamental to understanding energy transfer and heating in astrophysical systems. Collisionless interactions, such as resonant wave-par…
Pressure anisotropy and viscous heating in weakly collisional plasma turbulence
Jonathan Squire, Matthew W Kunz, Lev Arzamasskiy +3
Pressure anisotropy can strongly influence the dynamics of weakly collisional, high-beta plasmas, but its effects are missed by standard magnetohydrodynamics (MHD). Small changes t…
Parker Solar Probe: Four Years of Discoveries at Solar Cycle Minimum
N. E. Raouafi, L. Matteini, J. Squire +54
Launched on 12 Aug. 2018, NASA's Parker Solar Probe had completed 13 of its scheduled 24 orbits around the Sun by Nov. 2022. The mission's primary science goal is to determine the…
