Redefining SAR Arc Generation: The Competing Roles of Magnetospheric and Ionospheric Energy Injection

AGU Advances, Volume 6, Issue 6, December 2025.
Abstract Stable auroral red (SAR) arcs are luminous subauroral emissions produced by the collisional excitation of oxygen atoms during geomagnetically active times. While traditionally attributed to inner magnetospheric electron heating, recent observations and simulations challenge the exclusivity of this mechanism.

On the self-consistent model of the axisymmetric radio pulsar magnetosphere

, 1998
We consider a model of axisymmetric neutron star magnetosphere. In our approach, the current density in the region of open field lines is constant and the returning current flows in a narrow layer along the separatrix.

Chorus Wave–Driven Electron Dynamics in the Van Allen Belts: From Coherence to Diffusion

AGU Advances, Volume 6, Issue 6, December 2025.
Abstract The Van Allen radiation belts contain relativistic electrons trapped by Earth's magnetic field, posing serious risks to spacecraft. Chorus waves are known to accelerate these electrons via resonant interactions, but these interactions are inherently nonlinear and coherent.

Solar Wind—Magnetosphere Coupling Functions: Pitfalls, Limitations, and Applications

Space Weather, 2022
Solar wind‐magnetosphere coupling functions have now been in use for almost 50 years. In that time, a very large number of formulations have been proposed.

The modulation of SiO maser polarization by Jovian planets

, 2008
Searching for planets in the atmosphere of AGB stars is difficult, due to confusion with the stellar wind and pulsations. The aim here is to provide a complementary strategy for planet search in such a dense environment.

Circulation of Heavy Ions and Their Dynamical Effects in the Magnetosphere: Recent Observations and Models

, 2014
Knowledge of the ion composition in the near-Earth’s magnetosphere and plasma sheet is essential for the understanding of magnetospheric processes and instabilities.

Explicit IMF By Dependence in Geomagnetic Activity: Modulation of Precipitating Electrons

Geophysical Research Letters, 2020
The most important driver of geomagnetic activity is the north–south ( Bz) component of the interplanetary magnetic field (IMF), which dominates the solar wind‐magnetosphere coupling and all solar wind coupling functions.

Kinetic-scale magnetic turbulence and finite Larmor radius effects at Mercury

, 2011
We use a nonstationary generalization of the higher-order structure function technique to investigate statistical properties of the magnetic field fluctuations recorded by MESSENGER spacecraft during its first flyby (01/14/2008) through the near Mercury ...

A Variational Approach for Modeling the Inductive Response of Earth's Mantle to Time‐Varying External Geomagnetic Source

Earth and Space Science, Volume 12, Issue 12, December 2025.
Abstract A mathematical and numerical framework is developed for modeling Earth's magnetic field and optimizing the trajectory of the whole system using geomagnetic observations. The conventional approach is adopted to model Earth's magnetic field in the source‐free region via the Gauss coefficient, for which the fast dynamical component for the mantle‐
