The Speed of Interplanetary Shocks Through the Magnetosheath: A Toy Model
Geophysical Research Letters, Volume 52, Issue 7, 16 April 2025.Abstract Before interacting with the magnetosphere, an interplanetary shock travels through the magnetosheath where its speed and shape are modified. Previous studies have reported widely different answers to the question of the speed of an interplanetary shock in the magnetosheath. Observational studies generally answer this question “macroscopically”,

Boundary Condition for the Electric Field in Earth's Core Models With Conducting Boundaries
Geophysical Research Letters, Volume 52, Issue 7, 16 April 2025.Abstract The Earth's core flows are governed by magnetohydrodynamic equations, where boundary conditions determine how the electric field in the liquid core relates to that in the conducting boundaries. In the Earth's core, the no‐slip condition implies continuity of the electric field, following the continuous horizontal velocity field.

Sub‐Auroral Heating at Jupiter Following a Solar Wind Compression
Geophysical Research Letters, Volume 52, Issue 7, 16 April 2025.Abstract Jupiter's polar aurorae deliver significant heating at the poles, thought to spread across the planet through atmospheric winds. Additionally, ground‐based Keck observations have revealed a large‐scale high‐temperature region, spatially distinct from the aurorae.

The Eddy Flux Transport of the Magnetohydrodynamic Quasi‐Geostrophic Disturbances
Geophysical Research Letters, Volume 52, Issue 7, 16 April 2025.Abstract The classic Eliassen‐Palm (E‐P) flux in the geophysical fluid dynamics is a vector to qualify the eddy momentum and heat flux transport by Rossby waves in the latitude‐height plane. In this investigation, we derive two magnetic E‐P fluxes to quantify the eddy energy transport by magnetic Rossby waves by using magnetohydrodynamic quasi ...

Advanced Functional Materials, Volume 35, Issue 14, April 3, 2025.An ultrathin polarizonic metasurface achieves multiband camouflage and stealth with near‐perfect ultraviolet (UV) absorption, visible light blending, and infrared signature masking. Leveraging earth‐abundant materials, this design creates a reflective color palette through polarizonic effects, integrating transparent and non‐plasmonic materials.

Non-unique solutions for electron MHD [PDF]
arXivWe consider the electron magnetohydrodynamics (MHD) equation on the 3D torus $\mathbb T^3$. For a given smooth vector field $H$ with zero mean and zero divergence, we can construct a weak solution $B$ to the electron MHD in the space $L^\gamma_tW^{1,p}_x$ for appropriate $(\gamma, p)$ such that $B$ is arbitrarily close to $H$ in this space.
