Non-universality of the Turbulent Spectra at Sub-ion Scales in the Solar Wind: Dispersive Effects versus the Doppler Shift

The Astrophysical Journal, 2023
Large surveys of the power spectral density of the magnetic fluctuations in the solar wind have reported different slope distributions at MHD, sub-ion and sub-electron scales: the smaller the scale, the broader the distribution.

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

The 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.

Turbulence development behind the bow shock during disturbed and undisturbed solar wind

Solar-Terrestrial Physics
Magnetosheath is a transition layer between the solar wind and the magnetosphere and may contribute to the geoeffectiveness of various large-scale interplanetary phenomena.

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

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

INFLUENCE OF THE SOLAR WIND ON INTERFEROMETRIC OBSERVATIONS AT THE DECAMETER WAVELENGTHS [PDF]

Radio Physics and Radio Astronomy, 2020
Purpose: The effect of the Earth’s ionosphere and interplanetary plasma on the radio astronomy observations, in particular, interferometric ones, at decameter waves has been investigated.

Efficiency of Electromagnetic Energy Transfer From Solar Wind to Ionosphere Through Magnetospheric Ultra‐Low Frequency Waves

Geophysical Research Letters, Volume 53, Issue 1, 16 January 2026.
Abstract Ultra‐low frequency (ULF) waves are a ubiquitous carrier of energy in geospace. However, their efficiency in transferring solar wind energy into the upper atmosphere remains a fundamental and not well‐understood question. This is due to their global presence, which cannot be fully quantified by spatially limited observations, and the need for ...

Spatial Distributions of Energetic Electrons and Energetic Ions in the Tail Reconnection Region: Cluster Observations and PIC Simulations

Geophysical Research Letters, Volume 53, Issue 1, 16 January 2026.
Abstract High‐energy particles are prevalent in space, and magnetic reconnection is one of the physical processes responsible for their generation. The heating and acceleration of ions and electrons typically occur respectively in the ion diffusion region and the electron diffusion region.

Interplay of Large-scale Drift and Turbulence in the Heliospheric Propagation of Solar Energetic Particles

The Astrophysical Journal
The gradient and curvature of the Parker spiral interplanetary magnetic field give rise to curvature and gradient guiding-center drifts on cosmic rays (CRs). The plasma turbulence present in interplanetary space is thought to suppress the drifts; however,

Different Transient Phenomena at the Edges of Traveling Foreshocks

Journal of Geophysical Research: Space Physics, Volume 131, Issue 1, January 2026.
Abstract Past kinetic simulations and spacecraft observations have shown that traveling foreshocks (TFs) are bounded by either foreshock compressional boundaries (FCBs) or foreshock bubbles (FBs). Here we present four TFs with a different kind of structure appearing at one of their edges.

Heliospheric Diffusion of Stochastic Parker Spirals in Radially Evolving Solar Wind Turbulence

The Astrophysical Journal
 We present a stochastic field line mapping model where the interplanetary magnetic field lines are described by a density distribution function satisfying a Fokker–Planck equation that is solved numerically.
