Analytical Modeling of Hot Ion Interchange Injections in Saturn's Magnetosphere

Journal of Geophysical Research: Space Physics, Volume 131, Issue 9, September 2026.
Abstract Cassini's CHarge Energy Mass Spectrometer (CHEMS) instrument collected energetic plasma data from 2004 to 2017, including hundreds of observations of small‐scale nearly dispersionless “local” injection events into the inner magnetosphere. This study assesses whether these interchange‐like injections are a channel‐like structure still connected

Statistical Scale Analyses of a Diurnal Periodicity in Auroral Kilometric Radiation, Observed by Wind/WAVES

Journal of Geophysical Research: Space Physics, Volume 131, Issue 9, September 2026.
Abstract The Earth's strongest natural radio emission is Auroral Kilometric Radiation (AKR), which is correlated with auroral intensity, and is a barometer for space weather. AKR is generated by the electron cyclotron maser instability, with sources on auroral field lines. Previous work on AKR and radio emissions from other planets (or stars) points to

Can Solar Cyclic Variability Mimic Extreme Solar Particle (Miyake) Events in Radiocarbon?

Journal of Geophysical Research: Space Physics, Volume 131, Issue 9, September 2026.
Abstract Rapid, strong enhancements in Δ14 ${{\Delta }}^{14}$C in the Earth's atmosphere, known as Miyake events, rarely occurred over the past millennia, pointing to major radiation storms affecting Earth. They are produced by extreme solar particle events (ESPEs) and are separated by an order‐of‐magnitude gap in the strength from directly observed ...

Earthward Transport of Lunar Metallic Ions: Implications of Heavy Ions in the Magnetosphere

Journal of Geophysical Research: Space Physics, Volume 131, Issue 9, September 2026.
Abstract Low‐charge‐state heavy ions in Earth's magnetosphere were thought to originate from the ionosphere. However, Observations from the Geotail mission have detected the presence of singly charged metallic ions, such as Fe+ ${\mathrm{F}\mathrm{e}}^{+}$, whose abundances vary depending on the Moon's location, alongside their density ratios to O ...

Impacts of the GDS 2018 Global Dust Storm on Martian Ionosphere‐Thermosphere Coupling via Atmospheric Tides

Journal of Geophysical Research: Space Physics, Volume 131, Issue 9, September 2026.
Abstract In this study, we investigate the ionospheric and thermospheric responses to the 2018 Mars global dust storm (GDS 2018) by examining atmosphere–ionosphere coupling through tidal structures. Using Mars Atmosphere and Volatile EvolutioN Neutral Gas and Ion Mass Spectrometer observations, we analyze tidal amplitudes, phases, and inter‐species ...

Saturn's Auroral Dusk Sector Magnetosphere‐Ionosphere Coupling During Cassini's Proximal Orbits

Journal of Geophysical Research: Space Physics, Volume 131, Issue 9, September 2026.
Abstract The final twenty‐two low‐altitude passes of the Cassini spacecraft enabled the determination of Saturn's field‐aligned currents (FACs) from magnetometer measurements at lower altitudes than previously achieved. We investigate southern dusk‐side FAC behavior with four objectives: how in situ MAG measurements compare to the highly variable ...
