Evidence for the helicity barrier from measurements of the turbulence transition range in the solar wind
J. R. McIntyre, C. H. K. Chen, J. Squire +2
The means by which the turbulent cascade of energy is dissipated in the solar wind, and in other astrophysical systems, is a major open question. It has recently been proposed that…
Properties of an interplanetary shock observed at 0.07 and 0.7 Astronomical Units by Parker Solar Probe and Solar Orbiter
D. Trotta, A. Larosa, G. Nicolaou +23
The Parker Solar Probe (PSP) and Solar Orbiter (SolO) missions opened a new observational window in the inner heliosphere, which is finally accessible to direct measurements. On Se…
The Evolution of the 1/f Range Within a Single Fast-Solar-Wind Stream Between 17.4 and 45.7 Solar Radii
Nooshin Davis, B. D. G. Chandran, T. A. Bowen +7
The power spectrum of magnetic-field fluctuations in the fast solar wind ($V_{\rm SW}> 500 \mbox{ km} \mbox{ s}^{-1}$) at magnetohydrodynamic (MHD) scales is characterized by two d…
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…
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…
The Near-Sun Streamer Belt Solar Wind: Turbulence and Solar Wind Acceleration
C. H. K. Chen, B. D. G. Chandran, L. D. Woodham +8
The fourth orbit of Parker Solar Probe (PSP) reached heliocentric distances down to 27.9 Rs, allowing solar wind turbulence and acceleration mechanisms to be studied in situ closer…
The Solar Orbiter Science Activity Plan: translating solar and heliospheric physics questions into action
I. Zouganelis, A. De Groof, A. P. Walsh +182
Solar Orbiter is the first space mission observing the solar plasma both in situ and remotely, from a close distance, in and out of the ecliptic. The ultimate goal is to understand…
Dust impact voltage signatures on Parker Solar Probe: influence of spacecraft floating potential
S. D. Bale, K. Goetz, J. W. Bonnell +15
When a fast dust particle hits a spacecraft, it generates a cloud of plasma some of which escapes into space and the momentary charge imbalance perturbs the spacecraft voltage with…
The rotation angle distribution underlying magnetic field fluctuations in the 1/f range of solar wind turbulent spectra
L. Matteini, D. Stansby, T. S. Horbury +1
We discuss properties of large amplitude magnetic field fluctuations during fast Alfvenic solar wind streams, focussing on the statistics of the rotation angle between consecutive…
[Plasma 2020 Decadal] The Material Properties of Weakly Collisional, High-Beta Plasmas
M. W. Kunz, J. Squire, S. A. Balbus +14
This white paper, submitted for the Plasma 2020 Decadal Survey, concerns the physics of weakly collisional, high-beta plasmas -- plasmas in which the thermal pressure dominates ove…
Parallel Electric Field Spectrum of Solar Wind Turbulence
F. S. Mozer, C. H. K. Chen
By searching through more than 10 satellite-years of THEMIS and Cluster data, three reliable examples of parallel electric field turbulence in the undisturbed solar wind have been…
