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…
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…
Identification of Magnetic Flux Ropes from Parker Solar Probe Observations during the First Encounter
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…
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…
[Plasma 2020 Decadal] The essential role of multi-point measurements in turbulence investigations: the solar wind beyond single scale and beyond the Taylor Hypothesis
W. H. Matthaeus, R. Bandyopadhyay, M. R. Brown +46
This paper briefly reviews a number of fundamental measurements that need to be made in order to characterize turbulence in space plasmas such as the solar wind. It has long been k…
[Plasma 2020 Decadal] Disentangling the Spatiotemporal Structure of Turbulence Using Multi-Spacecraft Data
J. M. TenBarge, O. Alexandrova, S. Boldyrev +26
This white paper submitted for 2020 Decadal Assessment of Plasma Science concerns the importance of multi-spacecraft missions to address fundamental questions concerning plasma tur…
Evidence for Electron Landau Damping in Space Plasma Turbulence
C. H. K. Chen, K. G. Klein, G. G. Howes
How turbulent energy is dissipated in weakly collisional space and astrophysical plasmas is a major open question. Here, we present the application of a field-particle correlation…
Predictions for the First Parker Solar Probe Encounter
B. van der Holst, W. B. Manchester, K. G. Klein +1
We examine Alfvén Wave Solar atmosphere Model (AWSoM) predictions of the first Parker Solar Probe (PSP) encounter. We focus on the 12-day closest approach centered on the 1st perih…
The multi-scale nature of the solar wind
Daniel Verscharen, Kristopher G. Klein, Bennett A. Maruca
The solar wind is a magnetized plasma and as such exhibits collective plasma behavior associated with its characteristic spatial and temporal scales. The characteristic length scal…
