Relevance of Murchison Widefield Array Interplanetary Scintillation Observations to Heliospheric Transient Catalogs

open access: yesSpace Weather, Volume 23, Issue 12, December 2025.
Abstract We have conducted a comprehensive comparison of interplanetary scintillation (IPS) observations taken by the Murchison Widefield Array (MWA) with several heliospheric transient event catalogs, over a time period of 7 months during solar minimum.

Axial Flux Evolution of Small-scale Magnetic Flux Ropes from 0.06 to 10 au

open access: yesThe Astrophysical Journal Letters
Small-scale magnetic flux ropes (SMFRs) fill much of the solar wind, but their origin and evolution are debated. We apply our recently developed, improved Grad–Shafranov algorithm for the detection and reconstruction of SMFRs to data from Parker Solar ...

Global Occurrence of Kelvin‐Helmholtz Vortices at Mars

open access: yesGeophysical Research Letters, Volume 52, Issue 22, 28 November 2025.
Abstract We analyzed six Kelvin‐Helmholtz (K‐H) vortex events from Mars Atmosphere and Volatile EvolutioN (MAVEN) measurements. We found that fully developed vortices can occur at Mars' equatorial flanks and in the southern hemisphere, while they were previously observed only in the northern hemisphere.

Correlation functions of small-scale fluctuations of the interplanetary magnetic field

open access: yes, 2010
The Interplanetary Magnetic Field shows complex spatial and temporal variations. Single spacecraft measurements reveal only a one dimensional section of this rich four dimensional phenomenon.

Solar Orbiter Observations of a Self‐Consistent Ion‐Scale Magnetic Hole at 0.9AU

open access: yesGeophysical Research Letters, Volume 52, Issue 22, 28 November 2025.
Abstract Magnetic holes (MHs) are localized structures characterized by magnetic field depressions, accompanied by an enhancement in plasma thermal pressure. These pressure‐balanced structures span a broad range of scales in space, from fluid to kinetic regimes. The kinetic‐scale MHs are ubiquitous in the solar wind; however, the exploration is limited

Effects of Waves on the Spectral Anisotropy of the Transition Range in Solar Wind Turbulence

open access: yesThe Astrophysical Journal
In the transition range of the solar wind turbulence, the magnetic spectrum has been observed to be strongly anisotropic with respect to the local mean field. However, the generation mechanism of the anisotropy remains not well understood.

TRANSPORT EQUATION FOR MHD TURBULENCE: APPLICATION TO PARTICLE ACCELERATION AT INTERPLANETARY SHOCKS

open access: yesThe Astrophysical Journal, 2009
The aim of the present paper is to unify the various transport equations for turbulent waves that are used in different areas of space physics. Here, we mostly focus on the magnetohydrodynamic turbulence, in particular the Alfvenic turbulence. The applied methods, however, are general and can be extended to other forms of turbulence, for example the ...

Fractal structure of the interplanetary magnetic field [PDF]

open access: yes
Under some conditions, time series of the interplanetary magnetic field strength and components have the properties of fractal curves. Magnetic field measurements made near 8.5 AU by Voyager 2 from June 5 to August 24, 1981 were self-similar over time ...

Radial Evolution of Turbulence Spectra on the Jovian Magnetosheath Flanks: Juno Observations

open access: yesThe Astrophysical Journal
The Jovian magnetosheath provides a unique environment for examining the radial evolution of magnetosheath turbulence due to its large spatial extent.

Linking Turbulent Interplanetary Magnetic Field Fluctuations and Current Sheets

open access: yesUniverse
The study aims to understand the role of solar wind current sheets (CSs) in shaping the spectrum of turbulent fluctuations and driving dissipation processes in space plasma. Local non-adiabatic heating and acceleration of charged particles in the solar wind is one of the most intriguing challenges in space physics.
