Deriving IMF Properties From Mars Express Heavy Pickup Ion Measurements

Geophysical Research Letters, Volume 52, Issue 11, 16 June 2025.
Abstract We present Mars Express (MEX) observations of heavy pickup ions (HPUI) at Mars and a new method to derive interplanetary magnetic field (IMF) properties. The MEX HPUI measurements were organized using the upstream IMF directions measured by the Mars Atmosphere and Volatile EvolutioN (MAVEN) mission.

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.

Dynamos in precessing cubes

New Journal of Physics, 2016
We investigate with numerical simulations the dynamo properties of liquid flows in precessing cubes. There are some similarities with the flow in precessing spheres. Instabilities in the form of triad resonances are observed.

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.

Statistical Observations in Support of Bow Shock Current Closure to Earth's High‐Latitude Ionosphere During Non‐Zero IMF By

Journal of Geophysical Research: Space Physics, Volume 130, Issue 6, June 2025.
Abstract The bow shock current (BSC) plays an important role in supplying the magnetosphere with solar wind energy, in particular during times of low solar wind magnetosonic Mach numbers. Since the magnetic pile‐up in the magnetosheath has to be maintained, the BSC cannot close locally, but must instead connect to magnetospheric current systems ...

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).

Positivity-Preserving Finite Difference WENO Schemes with Constrained Transport for Ideal Magnetohydrodynamic Equations [PDF]

, 2015
In this paper, we utilize the maximum-principle-preserving flux limiting technique, originally designed for high order weighted essentially non-oscillatory (WENO) methods for scalar hyperbolic conservation laws, to develop a class of high order ...

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 ...
