Plasma Waves near the Electron Cyclotron Frequency in the near-Sun Solar Wind

David M. Malaspina, Jasper Halekas, Laura Bercic +17

Data from the first two orbits of the Sun by Parker Solar Probe reveal that the solar wind sunward of 50 solar radii is replete with plasma waves and instabilities. One of the most…

Proton Temperature Anisotropy Variations in Inner Heliosphere Estimated with First Parker Solar Probe Observations

Jia Huang, Justin C. Kasper, Daniel Vech +27

We report proton temperature anisotropy variations in the inner heliosphere with Parker Solar Probe (PSP) observations. Using a linear fitting method, we derive proton temperature…

Electron energy partition across interplanetary shocks: II. Statistics

Lynn B. Wilson, Li-Jen Chen, Shan Wang +10

A statistical analysis of 15,210 electron velocity distribution function (VDF) fits, observed within 2 hours of 52 interplanetary (IP) shocks by the spacecraft near 1 A…

Scattering of energetic electrons by heat-flux-driven whistlers in flares

G. T. Roberg-Clark, O. V. Agapitov, J. F. Drake +1

The scattering of electrons by heat-flux-driven whistler waves is explored with a particle-in-cell (PIC) simulation relevant to the transport of energetic electrons in flares. The…

Nonlinear evolution of the whistler heat flux instability

Ilya V. Kuzichev, Ivan Y. Vasko, Angel Rualdo Soto-Chavez +4

We use the one-dimensional TRISTAN-MP particle-in-cell code to model the nonlinear evolution of the whistler heat flux instability that was proposed by Gary et al. (1999, 2000) to…

Self-induced Scattering of Strahl Electrons in the Solar Wind

Daniel Verscharen, Benjamin D. G. Chandran, Seong-Yeop Jeong +3

We investigate the scattering of strahl electrons by microinstabilities as a mechanism for creating the electron halo in the solar wind. We develop a mathematical framework for the…

Transition from ion-coupled to electron-only reconnection: Basic physics and implications for plasma turbulence

P. Sharma Pyakurel, M. A. Shay, T. D. Phan +9

Using kinetic particle-in-cell (PIC) simulations, we simulate reconnection conditions appropriate for the magnetosheath and solar wind, i.e., plasma beta (ratio of gas pressure to…
