Kinetic Scale Spectral Features of Cross Helicity and Residual Energy in the Inner Heliosphere
Daniel Vech, Justin C. Kasper, Kristopher G. Klein +17
In this Paper, we present the first results from the Flux Angle operation mode of the Faraday Cup instrument onboard Parker Solar Probe. The Flux Angle mode allows rapid measuremen…
Magnetic field kinks and folds in the solar wind
Anna Tenerani, Marco Velli, Lorenzo Matteini +18
Parker Solar Probe (PSP) observations during its first encounter at 35.7 have shown the presence of magnetic field lines which are strongly perturbed to the point that th…
The Enhancement of Proton Stochastic Heating in the near-Sun Solar Wind
Mihailo M. Martinović, Kristopher G. Klein, Justin C. Kasper +18
Stochastic heating is a non-linear heating mechanism driven by the violation of magnetic moment invariance due to large-amplitude turbulent fluctuations producing diffusion of ions…
The Solar Probe Cup on Parker Solar Probe
Anthony W. Case, Justin C. Kasper, Michael L. Stevens +18
The Solar Probe Cup (SPC) is a Faraday Cup instrument onboard NASA's Parker Solar Probe (PSP) spacecraft designed to make rapid measurements of thermal coronal and solar wind plasm…
Turbulence Transport Modeling and First Orbit Parker Solar Probe (PSP) Observations
Laxman Adhikari, Gary P. Zank, Lingling Zhao +8
Parker Solar Probe (PSP) achieved its first orbit perihelion on November 6, 2018, reaching a heliocentric distance of about 0.165 au (35.55 R). Here, we study the evolution…
Ion Scale Electromagnetic Waves in the Inner Heliosphere
Trevor Bowen, Alfred Mallet, Jia Huang +22
Understanding the physical processes in the solar wind and corona which actively contribute to heating, acceleration, and dissipation is a primary objective of NASA's Parker Solar…

L. -L. Zhao, G. P. Zank, L. Adhikari +17
The Parker Solar Probe (PSP) observed an interplanetary coronal mass ejection (ICME) event during its first orbit around the sun, among many other events. This event is analyzed by…
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…
Linear Stability in the Inner Heliosphere: Helios Reëvaluated
Kristopher G. Klein, Mihailo Martinovic, David Stansby +1
Wave-particle instabilities driven by departures from local thermodynamic equilibrium have been conjectured to play a role in governing solar wind dynamics. We calculate the statis…
Challenges and the next transformative steps in understanding plasma turbulence from the perspective of multi-spacecraft measurements
Li-Jen Chen, Naoki Bessho, Jay A. Bookbinder +18
We have become heavily reliant on electrical technologies, from power grids to GPS to wireless communication. Any disruption of these systems will have severe global consequences.…
A Case for Electron-Astrophysics
Daniel Verscharen, Robert T. Wicks, Olga Alexandrova +27
A grand-challenge problem at the forefront of physics is to understand how energy is transported and transformed in plasmas. This fundamental research priority encapsulates the con…
Strong Preferential Ion Heating is Limited to within the Solar Alfven Surface
Justin C Kasper, Kristopher G Klein
The decay of the solar wind helium to hydrogen temperature ratio due to Coulomb thermalization can be used to measure how far from the Sun strong preferential ion heating occurs. P…
Radial evolution of stochastic heating in low- solar wind
Mihailo M. Martinović, Kristopher G. Klein, Sofiane Bourouaine
We consider the radial evolution of perpendicular ion heating due to the violation of magnetic moment conservation caused by Alfven and kinetic Alfven wave turbulence. This process…
