Fundamental Poloidal Wave Event Extending From Midnight to Dawn

Journal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.
Abstract Fundamental poloidal (P1) waves are a class of magnetospheric standing Alfvén waves characterized by field line oscillations in the meridional plane. P1 waves are infrequently excited in the ring current region and are believed to be the source of giant pulsations (Pgs) observed on the ground. Pgs are mostly detected on the morning side with a

Low Frequency Extensions of Cyclotron Maser Instability‐Generated Radio Emission: A Statistical View From Cassini at Saturn

Journal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.
Abstract The Cassini spacecraft spent 13 years orbiting Saturn, quasi‐continuously measuring Saturn's radio emissions. One of the key elements of the radio spectrum at Saturn is the Saturn Kilometric Radiation (SKR), and several studies have been written on events called Low Frequency Extensions (LFEs) which represent strong, continuous extensions of ...

The Species‐ and Energy‐Dependent Effects of EMIC Waves on Ring Current Ions

Journal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.
Abstract Wave‐particle interactions are a major mechanism responsible for dissipating energy and redistributing particles within geospace. This study investigates the effects of electromagnetic ion cyclotron waves on ring current ions. We present a case study of the effects of EMIC waves on the ring current during the 15 August 2015 geomagnetic storm ...

Self‐Limiting of Artificial Electron Radiation Belts: Evidence From the Starfish Prime High‐Altitude Nuclear Explosion

Journal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.
Abstract The 1962 Starfish Prime high‐altitude 1.4‐megaton nuclear detonation injected large amounts of fission‐produced energetic electrons into the inner magnetosphere (L = 1.12), creating an intense artificial radiation belt that persisted for years. In this study, we revisit historical data from this unprecedented event to investigate the potential

Reconstructing Europa's Atmosphere From H2+ ${\mathbf{H}}_{\mathbf{2}}^{+}$ Pickup Ions Detected During the Juno PJ45 Flyby

Journal of Geophysical Research: Planets, Volume 131, Issue 8, August 2026.
Abstract We use a suite of single‐species (H2 ${\mathrm{H}}_{2}$) and multispecies (H2+O2+H+O ${\mathrm{H}}_{2}+{\mathrm{O}}_{2}+\mathrm{H}+\mathrm{O}$) Direct Simulation Monte Carlo models of Europa's atmosphere to interpret the H2+ ${\mathrm{H}}_{2}^{+}$ pickup ions detected by Juno at distances beyond 2 $2$ Europa radii RE $\left({R}_{E}\right ...
