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…
Direct Measurement of Diffusion Coefficients: Evidence for Diffusive Stochastic Heating in Collisionless Plasmas
Tamar Ervin, Trevor A. Bowen, Alfred Mallet +7
The paper presents a new method to directly measure velocity‑space diffusion coefficients from Parker Solar Probe data, using these measurements to evaluate stochastic versus reson…
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…
Perpendicular ion heating in turbulence and reconnection: magnetic moment breaking by coherent fluctuations
Alfred Mallet, Kristopher G. Klein, Benjamin D. G. Chandran +2
We study the interaction of an ion with a fluctuation in the electromagnetic fields that is localized in both space and time. We study the scale-dependence of the interaction in bo…
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…
Free Energy Sources of Ion-scale Waves Observed by Parker Solar Probe
Niranjana Shankarappa, Kristopher G. Klein, Mihailo M. MartinoviÄ +6
Parker Solar Probe (PSP) observes abundant circularly polarized ion-scale waves throughout the inner heliosphere. These waves are a signature of the interplay between plasma microi…
