The essential role of multi-point measurements in investigations of turbulence, three-dimensional structure, and dynamics: the solar wind beyond single scale and the Taylor Hypothesis
W. H. Matthaeus, S. Adhikari, R. Bandyopadhyay +49
Space plasmas are three-dimensional dynamic entities. Except under very special circumstances, their structure in space and their behavior in time are not related in any simple way…
Strategies for determining the cascade rate in MHD turbulence: isotropy, anisotropy, and spacecraft sampling
Yanwen Wang, Rohit Chhiber, Subash Adhikari +6
``Exact'' laws for evaluating cascade rates, tracing back to the Kolmogorov ``4/5'' law, have been extended to many systems of interest including magnetohydrodynamics (MHD), and co…
Magnetic field intermittency in the solar wind: PSP and SolO observations ranging from the Alfven region out to 1 AU
Nikos Sioulas, Zesen Huang, Marco Velli +17
and data are utilized to investigate magnetic field intermittency in the solar wind (SW). Small-scale intermittency is observed to radially strengthen…
Anisotropic Magnetic Turbulence in the Inner Heliosphere -- Radial Evolution of Distributions observed by Parker Solar Probe
Rohit Chhiber
Observations from Parker Solar Probe's first five orbits are used to investigate the helioradial evolution of probability density functions (PDFs) of fluctuations of magnetic field…
Isotropization and Evolution of Energy-Containing Eddies in Solar Wind Turbulence: Parker Solar Probe, Helios 1, ACE, WIND, and Voyager 1
Manuel Enrique Cuesta, Rohit Chhiber, Sohom Roy +6
We examine the radial evolution of correlation lengths perpendicular (\(λ_C^{\perp}\)) and parallel (\(λ_C^{\parallel}\)) to the magnetic-field direction, computed from solar wind…
Magnetic Switchback Occurrence Rates in the Inner Heliosphere: Parker Solar Probe and 1 au
Francesco Pecora, William H. Matthaeus, Leonardo Primavera +4
The subject of switchbacks, defined either as large angular deflections or polarity reversals of the magnetic field, has generated substantial interest in the space physics communi…
Intermittency in the Expanding Solar Wind: Observations from Parker Solar Probe (0.16au), Helios 1 (0.3-1au), and Voyager 1 (1-10au)
Manuel Enrique Cuesta, Tulasi N. Parashar, Rohit Chhiber +1
We examine statistics of magnetic field vector components to explore how intermittency evolves from near sun plasma to radial distances as large as 10 au. Statistics entering the a…
Sub-Alfvenic Solar Wind observed by PSP: Characterization of Turbulence, Anisotropy, Intermittency, and Switchback
R. Bandyopadhyay, W. H. Matthaeus, D. J. McComas +18
In the lower solar coronal regions where the magnetic field is dominant, the Alfven speed is much higher than the wind speed. In contrast, the near-Earth solar wind is strongly sup…
Statistical analysis of intermittency and its association with proton heating in the near Sun environment
Nikos Sioulas, Marco Velli, Rohit Chhiber +9
We use data from the first six encounters of Parker Solar Probe and employ the Partial Variance of Increments () method to study the statistical properties of coherent structu…
An Extended and Fragmented Alfvén Zone in the Young Solar Wind
Rohit Chhiber, William H. Matthaeus, Arcadi V. Usmanov +2
Motivated by theoretical, numerical, and observational evidence, we explore the possibility that the critical transition between sub-Alfvénic flow and super-Alfvénic flow in the so…
