Radial evolution of power spectra of interplanetary Alfvénic turbulence [PDF]

open access: yesJournal of Geophysical Research: Space Physics, 1982
The radial evolution of the power spectra of the MHD turbulence within the trailing edge of high‐speed streams in the solar wind has been investigated with the magnetic field data of HELIOS 1 and 2 for heliocentric distances between 0.3 and 0.9 AU. In the analyzed frequency range 2.8 · 10−4 ‐ 8.3 · 10−2 Hz the computed spectra have, near the earth ...

Observations of Waves and Structures by Frequency–Wavenumber Spectrum in Solar Wind Turbulence

open access: yesThe Astrophysical Journal, 2023
A well-known shortcoming of single-spacecraft spectral analysis is that only the 1D wavenumber spectrum can be observed, assuming the characteristic wave propagation speed is much smaller than the solar wind flow speed.

The influence of a mean magnetic field on three-dimensional magnetohydrodynamic turbulence

open access: yes, 1994
Building on results from two-dimensional magnetohydrodynamic (MHD) turbulence (Shebalin, Matthaeus & Montgomery 1983), the development of anisotropic states from initially isotropic ones is investigated numerically for fully three-dimensional ...

The Influence of Magnetic Turbulence on the Energetic Particle Transport Upstream of Shock Waves

open access: yesAtmosphere, 2021
Energetic particles are ubiquitous in the interplanetary space and their transport properties are strongly influenced by the interaction with magnetic field fluctuations.

Plasma Stability in Turbulent Magnetic Flux Ropes Downstream of a Collisionless Shock

open access: yesGeophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract How pre‐existing solar wind turbulence, and coherent structures such as magnetic flux ropes within it, influence the transition of plasma across a shock is still poorly understood. Recently, in situ observations from the Earth's magnetosheath have been used to study plasma stability against ion kinetic instabilities. In the turbulent flow, the

Influence of Solar Sails on Magnetic Field Measurements in Space Plasmas

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 6, June 2026.
Abstract Solar sail technology is ready to be deployed in a satellite mission carrying a science‐grade magnetometer. In preparation for such a mission, it is essential to characterize the interactions between the sail and the ambient plasma that could affect the magnetometer readings.

From the Sun to the Earth: The 13 May 2005 Coronal Mass Ejection [PDF]

open access: yes, 2010
We report the results of a multi-instrument, multi-technique, coordinated study of the solar eruptive event of 13 May 2005. We discuss the resultant Earth-directed (halo) coronal mass ejection (CME), and the effects on the terrestrial space environment ...

Turbulence and Polytropic Changes across Interplanetary Shocks Observed by the Parker Solar Probe

open access: yesThe Astrophysical Journal Letters
Interplanetary shocks play a critical role in solar wind dynamics, influencing the properties of turbulence and thermodynamic processes. In this study, we statistically analyze changes in turbulence characteristics and polytropic indices across 37 quasi ...

Transport of cross helicity and radial evolution of alfvenicity in the solar wind

open access: yes, 2004
A transport theory including cross helicity, magnetohydrodynamic(MHD) turbulence, and driving by shear and pickup ions, is applied to the radial evolution of the solar wind.
