The Effects of Non-Equilibrium Velocity Distributions on Alfvén Ion-Cyclotron Waves in the Solar Wind
Jada Walters, Kristopher G. Klein, Emily Lichko +3
In this work, we investigate how the complex structure found in solar wind proton velocity distribution functions (VDFs), rather than the commonly assumed two-component bi-Maxwelli…
HelioSwarm: A Multipoint, Multiscale Mission to Characterize Turbulence
Kristopher G. Klein, Harlan Spence, Olga Alexandrova +47
HelioSwarm (HS) is a NASA Medium-Class Explorer mission of the Heliophysics Division designed to explore the dynamic three-dimensional mechanisms controlling the physics of plasma…
Ion-Driven Instabilities in the Inner Heliosphere II: Classification and Multi-Dimensional Mapping
Mihailo M. Martinovic, Kristopher G. Klein
Linear theory is a well developed framework for characterizing instabilities in weakly collisional plasmas, such as the solar wind. In the previous instalment of this series, we an…
Quantifying the Energy Budget in the Solar Wind from 13.3-100 Solar Radii
J. S. Halekas, S. D. Bale, M. Berthomier +10
A variety of energy sources, ranging from dynamic processes like magnetic reconnection and waves to quasi-steady terms like the plasma pressure, may contribute to the acceleration…
Parker Solar Probe Observations of High Plasma Beta Solar Wind from Streamer Belt
Jia Huang, J. C. Kasper, Davin E. Larson +23
In general, slow solar wind from the streamer belt forms a high plasma beta equatorial plasma sheet around the heliospheric current sheet (HCS) crossing, namely the heliospheric pl…
Estimation of turbulent proton and electron heating rates via Landau damping constrained by Parker Solar Probe observations
Niranjana Shankarappa, Kristopher G. Klein, Mihailo M Martinović
The heating of ions and electrons due to turbulent dissipation plays a crucial role in the thermodynamics of the solar wind and other plasma environments. Using magnetic field and…
Parker Solar Probe: Four Years of Discoveries at Solar Cycle Minimum
N. E. Raouafi, L. Matteini, J. Squire +54
Launched on 12 Aug. 2018, NASA's Parker Solar Probe had completed 13 of its scheduled 24 orbits around the Sun by Nov. 2022. The mission's primary science goal is to determine the…
The Structure and Origin of Switchbacks: Parker Solar Probe Observations
Jia Huang, J. C. Kasper, L. A. Fisk +25
Switchbacks are rapid magnetic field reversals that last from seconds to hours. Current Parker Solar Probe (PSP) observations pose many open questions in regard to the nature of sw…
