Electron Structures in Titan's Induced Magnetosphere and Low‐Frequency Wave Activity

Journal of Geophysical Research: Planets, Volume 130, Issue 6, June 2025.
Abstract The interaction of Titan's ionosphere with Saturn's magnetosphere leads to a mix of perturbed electromagnetic fields and accelerated and thermalized plasma in the induced magnetosphere. The complexity of this region has been noted in previous studies.

Anomalous Substorm Signatures During Sudden Solar‐Wind Pressure Enhancements

Journal of Geophysical Research: Space Physics, Volume 130, Issue 6, June 2025.
Abstract Magnetospheric substorms, characterized by the rapid release of energy stored in the magnetotail, play a central role in space weather dynamics. These events are typically triggered by enhanced magnetic reconnection between the Earth's magnetic field and the interplanetary magnetic field (IMF).

MHD Simulations of Europa's Interaction With Jupiter's Magnetosphere During the Juno Flyby: Electron Beams in the Plasma Wake

Journal of Geophysical Research: Space Physics, Volume 130, Issue 6, June 2025.
Abstract In September 2022, the Juno mission performed its only close flyby of Europa and traversed the moon's wake at a minimum distance of ∼ ${\sim} $350 km. Among other findings, the Jovian Auroral Distributions Experiment (JADE) detector onboard the spacecraft discovered intense field‐aligned electron beams (∼ ${\sim} $30–300 eV) downstream of the ...

Review of Conductive Reciprocating Liquid Metal Magnetohydrodynamic Generators

Energies
Reciprocating liquid metal magnetohydrodynamic (MHD) power generation is a new MHD power generation method in which the working fluid is a single-phase liquid metal with a low melting point and high conductivity.

Variation of Model‐Predicted Reconnection Voltages Applied to Uranus' Dayside Magnetosphere

Journal of Geophysical Research: Space Physics, Volume 130, Issue 6, June 2025.
Abstract Uranus provides a key missing piece for fundamentally understanding solar wind‐magnetospheric interactions due to its location in the outer solar system. Whether the viscous‐like interaction overtakes global magnetic reconnection as the dominant process at the magnetopause of the outer planets remains unresolved.

Scaling laws of the plasma velocity in visco-resistive magnetohydrodynamic systems

Fundamental Plasma Physics
We consider a visco-resistive magnetohydrodynamic modelling of a steady-state incompressible tokamak plasma with a prescribed toroidal current drive, featuring constant resistivity η and viscosity ν.

Sizes of Active Galactic Nucleus Inhomogeneous Disks—Large in Microlensing, Small in Reverberation Mapping

The Astrophysical Journal
Magnetohydrodynamic turbulence can drive significant temperature fluctuations in the accretion disk of an active galactic nucleus (AGN). As a result, the disk can be highly inhomogeneous and has a half-light radius larger than the static Shakura and ...
