Turbulence in the outer heliosphere

F Fraternale, L Adhikari, H Fichtner, TK Kim… - Space Science …, 2022 - Springer
The solar wind (SW) and local interstellar medium (LISM) are turbulent media. Their
interaction is governed by complex physical processes and creates heliospheric regions …

Evolution of Solar Wind Turbulence from 0.1 to 1 au during the First Parker Solar Probe–Solar Orbiter Radial Alignment

A primary goal of the Parker Solar Probe (PSP) Mission is to answer the outstanding
question of how the solar corona plasma is heated to the high temperatures needed for the …

Spectral anisotropy in 2D plus slab magnetohydrodynamic turbulence in the solar wind and upper corona

GP Zank, M Nakanotani, LL Zhao… - The Astrophysical …, 2020 - iopscience.iop.org
The 2D+ slab superposition model of solar wind turbulence has its theoretical foundations in
nearly incompressible magnetohydrodynamics (NI MHD) in the plasma beta∼ 1 or≪ 1 …

Turbulent generation of magnetic switchbacks in the Alfvénic solar wind

M Shoda, BDG Chandran… - The Astrophysical …, 2021 - iopscience.iop.org
One of the most important early results from the Parker Solar Probe (PSP) is the ubiquitous
presence of magnetic switchbacks, whose origin is under debate. Using a three-dimensional …

A solar coronal hole and fast solar wind turbulence model and first-orbit Parker Solar Probe (PSP) observations

Abstract Parker Solar Probe (PSP) observed a large variety of Alfvénic fluctuations in the fast
and slow solar wind flow during its two perihelia. The properties of Alfvénic solar wind …

Linear Mode Decomposition in Magnetohydrodynamics Revisited

GP Zank, LL Zhao, L Adhikari… - The Astrophysical …, 2023 - iopscience.iop.org
Small-amplitude fluctuations in the magnetized solar wind are measured typically by a
