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.

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.

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

open access: yesThe 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

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

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.

The Density Distribution of Compressively Forced, Supersonic Turbulence Depends on the Driving Correlation Time

open access: yesThe Astrophysical Journal
Supersonic turbulence plays a critical role in shaping astrophysical systems, from molecular clouds to the circumgalactic medium. Key properties of this turbulence include the Mach number, driving scale, and nature of the driving mechanism, which can be ...
