Plasma pressure response to non-inductive current drive in axisymmetric visco-resistive magnetohydrodynamic steady states

Journal of Plasma Physics
We investigate self-consistent, steady-state axisymmetric solutions of an incompressible tokamak plasma using a visco-resistive magnetohydrodynamic model. A key contribution of this work is the formulation of Poisson’s equation that governs the pressure profile. Our analysis reveals that the current modelling fails to produce realistic pressure levels.

Reconstructing Europa's Atmosphere From H2+ ${\mathbf{H}}_{\mathbf{2}}^{+}$ Pickup Ions Detected During the Juno PJ45 Flyby

Journal of Geophysical Research: Planets, Volume 131, Issue 8, August 2026.
Abstract We use a suite of single‐species (H2 ${\mathrm{H}}_{2}$) and multispecies (H2+O2+H+O ${\mathrm{H}}_{2}+{\mathrm{O}}_{2}+\mathrm{H}+\mathrm{O}$) Direct Simulation Monte Carlo models of Europa's atmosphere to interpret the H2+ ${\mathrm{H}}_{2}^{+}$ pickup ions detected by Juno at distances beyond 2 $2$ Europa radii RE $\left({R}_{E}\right ...

Currents in the Martian Ionosphere: Cases Without Strong Crustal Magnetic Fields

Journal of Geophysical Research: Planets, Volume 131, Issue 8, August 2026.
Abstract The Martian ionosphere hosts complex current systems driven both by solar wind interactions and neutral wind dynamo processes. While the global patterns of these current systems have been statistically examined, their detailed structures and orientations remain poorly constrained.

Cosmic-Ray Feedback from Supernovae in a Parker-unstable Medium

The Astrophysical Journal
Supernova energy drives interstellar medium (ISM) turbulence and can help launch galactic winds. What difference does it make if 10% of the energy is initially deposited into cosmic rays?

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.

Improving Geomagnetic Perturbation Forecasts in the Southern Hemisphere via Kernel‐Based Encoding of Mirror Symmetry

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 4, August 2026.
Abstract Accurate forecasting of geomagnetic perturbations is essential for assessing space weather risk of geomagnetic activities. Thanks to decades of magnetometer observations from world‐wide distributed networks and upstream solar wind observations at L1, data‐driven modeling of global geomagnetic perturbations has become increasingly feasible ...

Laser energy asymmetry-driven deflection of Au plasma jets in half-cylinder target and its interaction with CH corona plasma

Nuclear Fusion
We investigate the formation of deflected gold $(\mathrm{Au})$ jets and their interaction with plastic $(\mathrm{CH})$ corona plasma, relevant to energy imbalances in the hohlraum for indirect drive inertial confinement fusion (ICF).

Active Flow Control of the Magnetohydrodynamic Flow in an Annular Linear Induction Pump by Modifying the Driving Electromagnetic Field

International Journal of Energy Research
The strong coupling between fluid and electromagnetic field in the annular linear induction pump (ALIP) can gradually amplify small disturbance in the fluid field into large‐scale vortices. The appearance of the vortices seriously affects the efficiency and reliability of the pump.

Optimization Algorithm for Determining the Source Surface Radius Based on Parker Solar Probe In Situ Measurements From Encounters 1 to 19

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 4, August 2026.
Abstract The Potential Field Source Surface (PFSS) extrapolation is a method for estimating the large scale coronal magnetic field from photospheric magnetograms. The source surface serves as the outer boundary of its solution domain, and is typically a spherical surface.

Real‐Time Prediction of Two Geomagnetic Storms Using Solar Orbiter as a Far Upstream Solar Wind Monitor

Space Weather, Volume 24, Issue 8, August 2026.
Abstract We present the first real‐time predictions of coronal mass ejection (CME) magnetic structure and resulting geomagnetic impact at Earth for two events using far‐upstream observations from Solar Orbiter during March 2024. While our approach assumes idealized conditions for CME propagation and scaling, in situ magnetic field data from upstream ...
