TL;DR: The Parker Solar Probe (PSP) mission was partially supported by the IS IS project (contract NNN06AA01C) and a subcontract to University of Delaware from Princeton University (SUB0000165) as mentioned in this paper.
Journal ArticleDOI
A review of relaxation and structure in some turbulent plasmas: magnetohydrodynamics and related models
TL;DR: A brief overview of hydrodynamic-like turbulence that characterizes the dynamics of plasmas in several parameter regimes is provided in this article, where an emphasis is placed on energy decay, spectra, relaxation processes, coherent structures, and higher statistics with selected applications in solar wind and laboratory Plasmas.
Journal ArticleDOI
Magnetic field strength distribution in interplanetary turbulence
TL;DR: In this paper, the authors derived the distribution of magnetic field magnitudes for the special case of a constant mean field and uncorrelated components having Gaussian distributions and compared it with a magnetic field magnitude distribution computed from the 1 AU Omni dataset.
Journal ArticleDOI

TL;DR: In this paper, the Parker Solar Probe (PSP) was used to study the inner heliosphere at distances closer to the Sun than previously possible, and the SEP events were selected using the 1 MeV proton intensities, and while small, they were sufficient to calculate proton and helium spectra from ~1 to ~10 MeV/nuc.

TL;DR: In this paper, the authors examined the spectral properties associated with laminar, anti-parallel reconnection using a 2.5D kinetic particle in cell simulation and found that both the reconnection rate and the energy spectrum exhibit three distinct phases: an initiation phase where the disconnection rate grows, a quasi-steady phase, and a declining phase where both the disconnections and energy spectrum decrease.
