CME -Associated Energetic Ions at 0.23 AU -- Consideration of the Auroral Pressure Cooker Mechanism Operating in the Low Corona as a Possible Energization Process
D. G. Mitchell, J. Giacalone, R. C. Allen +15
We draw a comparison between a solar energetic particle event associated with the release of a slow coronal mass ejection close to the sun, and the energetic particle population pr…
Cross Helicity Reversals In Magnetic Switchbacks
Michael D. McManus, Trevor A. Bowen, Alfred Mallet +17
We consider 2D joint distributions of normalised residual energy and cross helicity during one day of Parker Solar Probe's (PSP's) first encounter as a functi…
Enhanced Energy Transfer Rate in Solar Wind Turbulence Observed near the Sun from Parker Solar Probe
Riddhi Bandyopadhyay, M. L. Goldstein, B. A. Maruca +25
Direct evidence of an inertial-range turbulent energy cascade has been provided by spacecraft observations in heliospheric plasmas. In the solar wind, the average value of the deri…
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…
Measures of Scale Dependent Alfvénicity in the First PSP Solar Encounter
T. N. Parashar, M. L. Goldstein, B. A. Maruca +25
The solar wind shows periods of highly Alfvénic activity, where velocity fluctuations and magnetic fluctuations are aligned or anti-aligned with each other. It is generally agreed…
Switchbacks in the solar magnetic field: their evolution, their content, and their effects on the plasma, V2
F. S. Mozer1, O. V. Agapitov1, S. D. Bale1 +19
Switchbacks (rotations of the magnetic field) are observed on the Parker Solar Probe. Their evolution, content, and plasma effects are studied in this paper. The solar wind does no…
Observations of heating along intermittent structures in the inner heliosphere from PSP data
R. A. Qudsi, B. A. Maruca, W. H. Matthaeus +22
The solar wind proton temperature at 1-au has been found to be correlated with small-scale intermittent magnetic structures, i.e., regions with enhanced temperature are associated…
Clustering of Intermittent Magnetic and Flow Structures near Parker Solar Probe's First Perihelion -- A Partial-Variance-of-Increments Analysis
Rohit Chhiber, M. Goldstein, B. Maruca +23
During the Parker Solar Probe's (PSP) first perihelion pass, the spacecraft reached within a heliocentric distance of \(\sim 37~R_\odot\) and observed numerous magnetic and flow st…
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…
Predicting the Solar Wind at Parker Solar Probe Using an Empirically Driven MHD Model
T. K. Kim, N. V. Pogorelov, C. N. Arge +20
Since the launch on 2018/08/12, Parker Solar Probe (PSP) has completed its first and second orbits around the Sun, having reached down to 35.7 solar radii at each perihelion. In an…
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…
Energetic Particle Increases Associated with Stream Interaction Regions
C. M. S. Cohen, E. R. Christian, A. C. Cummings +34
The Parker Solar Probe was launched on 2018 August 12 and completed its second orbit on 2019 June 19 with perihelion of 35.7 solar radii. During this time, the Energetic particle I…
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…
[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…
