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

On the Formation of Super-Alfvénic Flows Downstream of Collisionless Shocks
Super-Alfvénic jets, with kinetic energy densities significantly exceeding that of the solar wind, are commonly generated downstream of Earth's bow shock under both high- and low-beta plasma conditions. In this study, we present theoretical evidence that

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

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

Dynamics of Slow Solar Wind Emerging from an Equatorial Coronal Hole
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.

Turbulent accumulation of interplanetary magnetic fluxes at the Venus ionopause
The accumulation of interplanetary magnetic fluxes around the Venus ionopause is examined in the light of the PVO magnetometer and plasma wave measurements. It is argued that convective electric currents within the ionosphere are not sufficient to account for the observed geometry of the magnetic profiles. It is suggested that turbulent flow conditions

MMS Observations of Electron Vorticity in the Earth’s Magnetosheath
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
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.

The effects of expansion and turbulence on the interplanetary evolution of a magnetic cloud
Coronal mass ejections represent the most extreme solar products, and show complex and dynamic structures when detected in situ. They are often preceded by a shock and carry a magnetic cloud organised as a flux rope, surrounded and permeated by turbulent fluctuations, and whose radial size expands during propagation.
