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…
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…
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…
