A powerful machine learning technique to extract proton core, beam and alpha-particle parameters from velocity distribution functions in space plasmas
Daniel Vech, Michael L. Stevens, Kristoff W. Paulson +4
Context: The analysis of the thermal part of velocity distribution functions (VDF) is fundamentally important for understanding the kinetic physics that governs the evolution and d…
Parker Solar Probe evidence for scattering of electrons in the young solar wind by narrowband whistler-mode waves
C. Cattell, A. Breneman, J. Dombeck +14
Observations of plasma waves by the Fields Suite and of electrons by the Solar Wind Electrons Alphas and Protons Investigation (SWEAP) on Parker Solar Probe provide strong evidence…
Proton Core Behaviour Inside Magnetic Field Switchbacks
Thomas Woolley, Lorenzo Matteini, Timothy S. Horbury +10
During Parker Solar Probe's first two orbits there are widespread observations of rapid magnetic field reversals known as switchbacks. These switchbacks are extensively found in th…
Parker Solar Probe observations of proton beams simultaneous with ion-scale waves
J. L. Verniero, D. E. Larson, R. Livi +19
Parker Solar Probe (PSP), NASA's latest and closest mission to the Sun, is on a journey to investigate fundamental enigmas of the inner heliosphere. This paper reports initial obse…
The Radial Dependence of Proton-scale Magnetic Spectral Break in Slow Solar Wind during PSP Encounter 2
Die Duan, Trevor A. Bowen, Christopher H. K. Chen +18
Magnetic field fluctuations in the solar wind are commonly observed to follow a power law spectrum. Near proton-kinetic scales, a spectral break occurs which is commonly interprete…
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…
