Observations of Energetic-Particle Population Enhancements along Intermittent Structures near the Sun from Parker Solar Probe

Riddhi Bandyopadhyay, W. H. Matthaeus, T. N. Parashar +31

Observations at 1 au have confirmed that enhancements in measured energetic particle fluxes are statistically associated with "rough" magnetic fields, i.e., fields having atypicall…

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…

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…

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…

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…

Solar flares observed by Rosetta at comet 67P

N. J. T. Edberg, F. L. Johansson, A. I. Eriksson +6

Context. The Rosetta spacecraft made continuous measurements of the coma of comet 67P/ Churyumov-Gerasimenko (67P) for more than two years. The plasma in the coma appeared very dyn…
