A Transport Theory of Turbulent Coronal Heating in General Geometry
Jonathan Squire, Benjamin D. G. Chandran, Toby Adkins +3
Magnetic geometry shapes how turbulence transports and dissipates energy in strongly magnetized plasmas. The solar corona, a maze of open and closed flux tubes with sharp transvers…
The influence of Parker spiral on the reflection-driven turbulence
Khurram Abbas, Jonathan Squire
The solar wind is observed to undergo substantial heating as it expands through the heliosphere, with measured temperature profiles exceeding those expected from adiabatic cooling.…
Stochastic Heating in the Sub-Alfvénic Solar Wind
Trevor A. Bowen, Tamar Ervin, Alfred Mallet +7
Collisionless dissipation of turbulence is important for heating plasmas in astrophysical, space physics, and laboratory environments, controlling energy, momentum and particle tra…
Formation of Magnetic Switchbacks via expanding Alfvén Waves
Trevor A. Bowen, Alfred Mallet, Corina I. Dunn +8
Context. Large-amplitude inversions of the solar wind's interplanetary magnetic field have long been documented; however, observations from the Parker Solar Probe (PSP) mission hav…
A Unified Phenomenology of Ion Heating in Low- Plasmas: Test-Particle Simulations
Zade Johnston, Jonathan Squire, Romain Meyrand
We argue that stochastic and resonant ion heating, often viewed as distinct processes in low- collisionless plasmas, are the far limits of a continuum controlled by nonlinear br…
Extreme heating of minor ions in imbalanced solar-wind turbulence
Michael F. Zhang, Matthew W. Kunz, Jonathan Squire +1
Minor ions in the solar corona are heated to extreme temperatures, far in excess of those of the electrons and protons that comprise the bulk of the plasma. These highly non-therma…
Evidence for the helicity barrier from measurements of the turbulence transition range in the solar wind
J. R. McIntyre, C. H. K. Chen, J. Squire +2
The means by which the turbulent cascade of energy is dissipated in the solar wind, and in other astrophysical systems, is a major open question. It has recently been proposed that…
Extended Cyclotron Resonant Heating of the Turbulent Solar Wind
Trevor A. Bowen, Ivan Y. Vasko, Stuart D. Bale +8
Circularly polarized, nearly parallel propagating waves are prevalent in the solar wind at ion-kinetic scales. At these scales, the spectrum of turbulent fluctuations in the solar…
