A Complete Theory for Nondiffusive Field Line Random Walk in Magnetic Turbulence

open access: yesThe Astrophysical Journal
Previous analytical and numerical investigations of the stochastic properties of field lines in magnetic turbulence have been based on determining the running field-line diffusion coefficient.

Spectral Anisotropy at Ion Scales in the Solar Wind Upstream of the Martian Bow Shock

open access: yesThe Astrophysical Journal
The spectral anisotropy of magnetic field fluctuations at ion scales in the solar wind upstream of the Martian bow shock remains poorly understood. In the solar wind near the Earth’s orbit, such anisotropy is known to be modulated by ion-scale waves ...

MMS Observations of Electron Vorticity in the Earth’s Magnetosheath

open access: yesThe Astrophysical Journal
The Earth’s magnetosheath serves as a natural laboratory to study the transition of highly turbulent fluctuations. The fundamental information about plasma turbulences can be examined observationally with the help of electron vorticity measurements. This

A Unifying Perspective on Kolmogorov Cascades in Solar Wind Plasma Turbulence

open access: yesThe Astrophysical Journal
It is argued that Kolmogorov cascades, including those affecting space weather in the solar wind plasma, can effectively be described by realizations of a continuous-time random walk.

Dynamics of Slow Solar Wind Emerging from an Equatorial Coronal Hole

open access: yesThe Astrophysical Journal
We present a three-dimensional reduced magnetohydrodynamics model to depict turbulence induced by Alfvén waves within the slow solar wind originating from an open magnetic field positioned in a coronal hole near the solar equator.

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.

Effects of Nonzero-frequency Fluctuations on Turbulence Spectral Observations

open access: yesThe Astrophysical Journal Letters
In situ observations of turbulence spectra in space plasmas are usually interpreted as wavenumber spectra, assuming that the fluctuation frequency is negligible in the plasma flow frame.

Comoving MHD simulations of the turbulent interplanetary evolution of a CME

open access: yesProceedings of the International Astronomical Union
Abstract Coronal mass ejections (CMEs) are eruptive solar events with great influence on Earth. They often carry coherent magnetic fields in the form of magnetic clouds as they propagate through the heliosphere. Despite being large-scale structures, CMEs are subject to meso-scale dynamical processes such as turbulence and magnetic ...

Turbulence and shocks in high-beta plasmas

open access: yes, 2014
High-beta plasmas are common in astrophysical environments, such as the intracluster medium (ICM) of galaxy clusters and the interplanetary medium (IPM) of the solar system.
