Origin of Silicic Magmatism at the Katla Volcanic Complex, South Iceland

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 6, June 2025.
Abstract The Katla volcano is a bimodal caldera complex within Iceland's basalt‐dominated Eastern Volcanic Zone. To unravel the petrogenesis of silica‐rich rocks from Katla, we provide new δ18O values for almost 60 basaltic, intermediate, and high‐silica eruptive rocks, including a number of partially melted felsic xenoliths.

Do Solar Eclipses Generate Propagating Ionospheric Perturbations?

Journal of Geophysical Research: Space Physics, Volume 130, Issue 6, June 2025.
Abstract Plasma depletion during a solar eclipse is well‐documented, but the generation of other forms of ionospheric perturbations by the impact of eclipses is controversial. This study aims to evaluate the generation of additional ionospheric perturbations through case studies of total solar eclipses observed across the United States on 21 August ...

Species‐Dependent and Azimuthally‐Directional Flux Changes of Dispersionless Ion Injections Inside Geosynchronous Orbit

Journal of Geophysical Research: Space Physics, Volume 130, Issue 6, June 2025.
Abstract Dispersionless injection, involving sudden, simultaneous flux enhancements of energetic particles over a broad range of energy, is a characteristic signature of the particles that are experiencing a significant acceleration and/or rapid inward transport process.

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).

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

Journal 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.
