Field‐Aligned Currents and Auroral Precipitation During the Terrestrial Alfvén Wing State

Geophysical Research Letters, Volume 52, Issue 12, 28 June 2025.
Abstract When sub‐Alfvénic (Alfvén Mach number MA< ${\mathrm{M}}_{A}< $1) plasmas impact Earth, Alfvén wings (AWs) develop. A Multiscale Atmosphere Geospace Environment simulation of the April 2023 storm, validated by Active Magnetosphere and Planetary Electrodynamics Response Experiment data, reveals the field‐aligned‐current (FAC) generation ...

Formation of the Bubble‐Like Ionospheric Super‐Depletion Structure (BLISS): MAGE Simulation of the September, 2017 Storm

Geophysical Research Letters, Volume 52, Issue 12, 28 June 2025.
Abstract This study investigates the formation of a newly identified storm‐time ionospheric phenomenon, the bubble‐like ionospheric super‐depletion structure (BLISS) in F‐region plasma densities. The observed BLISS initiates from the magnetic dip equator in the post‐sunset region and expands westward and poleward, reaching midlatitudes of ∼40°, which ...

Variability of Earth's Magnetopause and Bow Shock Locations Modeled via Multi‐Decade Solar Wind Observations

Geophysical Research Letters
Numerous studies have explored modeling the shape of Earth's magnetopause (MP) and bow shock (BS) as a function of incident solar wind conditions, utilizing either magnetohydrodynamic model data or observations of boundary crossings from orbiting ...

Properties of Magnetohydrodynamic Modes in Compressively Driven Plasma Turbulence

Physical Review X, 2020
We study properties of magnetohydrodynamic (MHD) eigenmodes by decomposing the data of MHD simulations into linear MHD modes—namely, the Alfvén, slow magnetosonic, and fast magnetosonic modes.

Global simulations of kinetic-magnetohydrodynamic processes with energetic electrons in tokamak plasmas

Nuclear Fusion, 2023
The energetic electrons (EEs) produced from auxiliary heatings have been found to destabilize various Alfven eigenmodes (AEs) in recent experiments. To investigate EE relevant kinetic-magnetohydrodynamic (MHD) processes, a global fluid-kinetic hybrid ...

Interplay Between a Foreshock Bubble and a Hot Flow Anomaly Forming Along the Same Rotational Discontinuity

Geophysical Research Letters, Volume 52, Issue 12, 28 June 2025.
Abstract Solar wind directional discontinuities can generate transient mesoscale structures such as foreshock bubbles and hot flow anomalies (HFAs) upstream of Earth's bow shock. These structures can have a global impact on near‐Earth space, so understanding their formation conditions is essential.

Dawn‐Dusk Asymmetry of Kelvin‐Helmholtz Vortices Along the Kronian Magnetopause

Geophysical Research Letters, Volume 52, Issue 11, 16 June 2025.
Abstract The Kelvin‐Helmholtz instability (KHI) at the Kronian magnetopause is an important process resulting from the interaction between the magnetosphere and the solar wind. The Kronian magnetosphere is rotationally driven, thus dawn‐dusk asymmetry has been observed in the KHI structures.

Analysis of Double‐Diffusive Transport and Entropy Generation in a Wavy Cylindrical Enclosure With Inner Heated Core: Effects of MHD and Radiation on Casson Cu─H2O Nanofluid

Energy Science &Engineering, Volume 13, Issue 6, Page 2810-2841, June 2025.
ABSTRACT This study investigates double‐diffusive transport and entropy generation in a wavy cylindrical enclosure containing Cu─H2O Casson nanofluid under magnetic field and thermal radiation effects. The governing equations were solved numerically using the finite element method with Galerkin formulation.

Review on Magneto‐Electrodeposition: Tailoring Material Properties for Enhanced Functionalities and Applications

MetalMat, Volume 2, Issue 2, June 2025.
Magneto‐electrodeposition (MED) is a proficient electrochemical method which uses a magnetic field during the electrodeposition process to influence ion transport and change the properties of the deposits. The Lorentz force influences the mass transport to the electrode surface by means of the magnetohydrodynamic effect (MHD) convection.
