Homotopic dynamic solution of hydrodynamic nonlinear natural convection containing superhydrophobicity and isothermally heated parallel plate with hybrid nanoparticles

open access: yesOpen Physics
The purpose of this work is to investigate the effect of thermal radiation on convective heat transfer for an electrically conducting hybrid nanofluid moving perpendicularly through a microchannel with parallel plates heated under isothermal conditions ...

Anomalous Substorm Signatures During Sudden Solar‐Wind Pressure Enhancements

open access: yesJournal 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).

Variation of Model‐Predicted Reconnection Voltages Applied to Uranus' Dayside Magnetosphere

open access: yesJournal of Geophysical Research: Space Physics, Volume 130, Issue 6, June 2025.
Abstract Uranus provides a key missing piece for fundamentally understanding solar wind‐magnetospheric interactions due to its location in the outer solar system. Whether the viscous‐like interaction overtakes global magnetic reconnection as the dominant process at the magnetopause of the outer planets remains unresolved.

Inferential Evidence for Surprathermal Electron Burst Intensification Due To Inverted‐V Precipitation via Inertial Alfvén Waves

open access: yesJournal of Geophysical Research: Space Physics, Volume 130, Issue 6, June 2025.
Abstract The auroral current and electrodynamic structures II sounding rocket mission launched two payloads from Andøya Rocket Range into a post‐dusk discrete auroral arc and observed field‐aligned electron dispersions near inverted‐V precipitation.

Non-unique solutions for electron MHD [PDF]

open access: yesarXiv
We 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.
