Investigating the Dependence of Normalized Reconnection Rate on Upstream Plasma Parameters

open access: yesGeophysical Research Letters, Volume 52, Issue 22, 28 November 2025.
Abstract We present the results of a multi‐event study of the normalized reconnection rate integrating events spanning the three primary regimes of reconnection observed by the Magnetospheric Multiscale mission. We utilize a new method for determining the normalized reconnection rate with fewer sources of uncertainty by estimating the aspect ratio and ...

Exploring Magnetic Reconnection in the Collisional Ionosphere of Mars With MAVEN

open access: yesGeophysical Research Letters, Volume 52, Issue 22, 28 November 2025.
Abstract Magnetic reconnection in collisional plasmas has been widely studied in solar and laboratory plasma disciplines, but in situ measurements in space plasmas have rarely been utilized to explore this reconnection regime. Here we study collisional effects on magnetic reconnection in the Martian ionosphere by analyzing in situ data obtained by the ...

Solving the Mystery of the Electron Radiation Belt at Uranus: Leveraging Knowledge of Earth's Radiation Belts in a Re‐Examination of Voyager 2 Observations

open access: yesGeophysical Research Letters, Volume 52, Issue 22, 28 November 2025.
Abstract Voyager 2 provided the only direct measurement of the radiation environment at Uranus and established the well‐accepted characterization of a system with a weaker ion radiation belt and surprisingly intense electron radiation belt. Recent re‐analysis of the flyby, however, suggests that these observations were not taken during normal solar ...

Cassini CAPS‐ELS Observations of Low‐Energy Electron Beams Within Enceladus Mid‐Latitude Flux Tubes

open access: yesGeophysical Research Letters, Volume 52, Issue 22, 28 November 2025.
Abstract The electrodynamic interaction between Saturn's magnetosphere and Enceladus accelerates electrons along magnetic field lines. These electrons propagate inside magnetic flux tubes connecting the moon to the giant planet, generating distinctive auroral hiss and auroral footprint signatures, both previously observed by the Cassini spacecraft.

Observations of Two‐Layers Spectrum Formed by Simultaneous H+ and He+ Anomalous Resonance With EMIC Waves

open access: yesGeophysical Research Letters, Volume 52, Issue 22, 28 November 2025.
Abstract In collisionless plasma environments, wave‐particle interactions facilitate efficient energy exchange between particles and phase‐coherent waves. Using Magnetospheric Multiscale mission observations, we report a novel two‐layers bridge‐like arcs structure in ion energy spectrum, formed by simultaneous nonlinear interactions between large ...
