Dynamics of Slow Solar Wind Emerging from an Equatorial Coronal Hole

The 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.

Linking Turbulent Interplanetary Magnetic Field Fluctuations and Current Sheets

Universe
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.

Plasmoids in Reconnecting Current Sheets: Solar and Terrestrial Contexts Compared

, 2008
Magnetic reconnection plays a crucial role in violent energy conversion occurring in the environments of high electrical conductivity, such as the solar atmosphere, magnetosphere, and fusion devices.

On the Formation of Super-Alfvénic Flows Downstream of Collisionless Shocks

The Astrophysical Journal
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

MMS Observations of Electron Vorticity in the Earth’s Magnetosheath

The 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

Fractal structure of the interplanetary magnetic field [PDF]

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 ...

Turbulent accumulation of interplanetary magnetic fluxes at the Venus ionopause

Geophysical Research Letters, 1981
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
