Nonlinear Gyrokinetic Simulation of the Magnetosphere‐Ionosphere Feedback Coupling

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract A nonlinear gyrokinetic simulation is applied to the magnetosphere‐ionosphere (M‐I) coupling system to investigate spontaneous growth of auroral structures and electron acceleration self‐consistently. Perturbations of electron density, potential and field‐aligned current in the auroral ionosphere develop through the feedback instability ...

Entropy Stable Finite Volume Approximations for Ideal Magnetohydrodynamics

, 2017
This article serves as a summary outlining the mathematical entropy analysis of the ideal magnetohydrodynamic (MHD) equations. We select the ideal MHD equations as they are particularly useful for mathematically modeling a wide variety of magnetized ...

Asymmetrically Distributed Kelvin‐Helmholtz Instability at Venusian Magnetosphere

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract The asymmetric distribution of Kelvin‐Helmholtz (KH) instability at Venusian ionopause is investigated using a multifluid model. Results show that KH instability distributes asymmetrically, preferentially developing in the −E (anti‐parallel to the interplanetary electric field) hemisphere.

The Evolution of Hot Flow Anomalies in Martian Space Environment

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract Hot Flow Anomalies (HFAs) are transient foreshock structures generated by solar wind discontinuity‐bow shock interactions, with their evolution only confirmed near Earth. Using MAVEN and Tianwen‐1 joint observations, we study the evolution of a Martian HFA event detected on 17 September 2022 (dayside by MAVEN, nightside by Tianwen‐1).

Mars' Ionospheric Response to the Onset and Early Phase of 20 May 2024 Solar Flare

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract Solar extreme ultraviolet (EUV, 10–100 nm) and X‐ray (<10 nm) photons are the primary ionization source for the dayside Mars ionosphere. Their fluxes, especially at short wavelengths, increase significantly during solar flares. Among the series of solar flares and solar storms encountered by Earth and Mars in May 2024, one of the strongest ...

Magnetic Vestibular Stimulation in Subjects with Unilateral Labyrinthine Disorders

Frontiers in Neurology, 2014
We recently discovered that static magnetic fields from high-strength MRI machines induce nystagmus in all normal humans, and that a magnetohydrodynamic (MHD) Lorentz force, derived from ionic currents in the endolymph and pushing on the cupula, best ...

Identification of Kelvin-Helmholtz generated vortices in magnetised fluids

Frontiers in Astronomy and Space Sciences
The Kelvin-Helmholtz Instability (KHI), arising from velocity shear across the magnetopause, plays a significant role in the viscous-like transfer of mass, momentum, and energy from the shocked solar wind into the magnetosphere.

Using sunRunner3D to interpret the global structure of the heliosphere from in situ measurements

Journal of Space Weather and Space Climate
Understanding the large-scale three-dimensional structure of the inner heliosphere, while important in its own right, is crucial for space weather applications, such as forecasting the time of arrival and propagation of coronal mass ejections (CMEs ...
