Data-constrained Magnetohydrodynamic Simulation of a Filament Eruption in the Decaying Active Region 13079 on a Global Scale

The Astrophysical Journal
Filaments are special plasma phenomena embedded in the solar atmosphere, characterized by unique thermodynamic properties and magnetic structures. Magnetohydrodynamic (MHD) simulations are useful to investigate the eruption mechanisms of filaments.

Unveiling the Global Characteristics of Turbulence in the Venusian Space Environment

Geophysical Research Letters
Turbulence plays a crucial role in energy transfer from large to small scales in solar wind‐Venus interaction. Observations have identified magnetic field fluctuations and turbulence in the Venusian space environment. However, due to limited observations
