Intermittent turbulence as the driver of stochastic heating in the near-Sun solar wind
Tamar Ervin, Trevor A. Bowen, Alfred Mallet +9
Understanding the mechanism by which the energy is dissipated at small scales to heat the outer corona and expanding solar wind, is a primary goal of the Parker Solar Probe (PSP) m…
Physics of Circular Polarized Ion-Scale Waves in Hybrid Simulations of Alfvénic Fluctuations
Hai Yang Harry Qian, Trevor A. Bowen, Carlos A. Gonzalez +5
Ion cyclotron waves (ICW) and fast magnetosonic/whistler waves (FMW) are fundamental electromagnetic modes at ion kinetic scales, yet their generation mechanisms and roles in plasm…
The Second Quadratic Invariant of Astrophysical Gyrokinetics
Benjamin D. G. Chandran, Alfred Mallet, Romain Meyrand
We show that gyrokinetics in a spatially uniform equilibrium (or `astrophysical gyrokinetics') possesses a previously unknown quadratic invariant, which we call the gyrokinetic hel…
Direct Measurement of Diffusion Coefficients: Evidence for Diffusive Stochastic Heating in Collisionless Plasmas
Tamar Ervin, Trevor A. Bowen, Alfred Mallet +7
Open questions in collisionless plasma dissipation can be addressed using space-based observations in different astrophysical environments, with implications for both astrophysical…
Evolution and Impact of Switchbacks Throughout the Heliosphere
Alfred Mallet, Chen Shi, Anna Tenerani +23
Magnetic switchbacks are large-amplitude fluctuations in the interplanetary magnetic field, and appear frequently in the near-Sun solar wind explored recently by Parker Solar Probe…
Generation and Expansion-Driven Growth of Switchbacks in the Outer Solar Corona and Solar Wind
Nikos Sioulas, Marco Velli, Chen Shi +6
We analyze \emph{Parker Solar Probe} and \emph{Solar Orbiter} measurements of magnetic-field reversals (``switchbacks'') across the Alfvén surface (), where is t…
On the Propagation and Damping of Alfvenic Fluctuations in the Outer Solar Corona and Solar Wind
Nikos Sioulas, Marco Velli, Chen Shi +17
We analyze \textit{Parker Solar Probe} and \textit{Solar Orbiter} observations to investigate the propagation and dissipation of Alfvénic fluctuations from the outer corona to 1~AU…
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…
Scale-Dependent Dynamic Alignment in MHD Turbulence: Insights into Intermittency, Compressibility, and Imbalance Effects
Nikos Sioulas, Marco Velli, Alfred Mallet +7
Scale-Dependent Dynamic Alignment (SDDA) in Elsässer field fluctuations is theorized to suppress nonlinearities and modulate the energy spectrum. Limited empirical evidence exists…
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…
Viriato: a Fourier-Hermite spectral code for strongly magnetised fluid-kinetic plasma dynamics
N. F. Loureiro, W. Dorland, L. Fazendeiro +4
We report on the algorithms and numerical methods used in Viriato, a novel fluid-kinetic code that solves two distinct sets of equations: (i) the Kinetic Reduced Electron Heating M…
