Derivation of the Two‐Dimensional Distribution of Low‐Energy Electron Precipitation From 630‐nm All‐Sky Auroral Images and Its Application to the Polar Cap Boundary Near Midnight

Journal of Geophysical Research: Space Physics, Volume 131, Issue 1, January 2026.
Abstract We present a methodology for deriving the horizontal two‐dimensional distribution of low‐energy electron precipitation, specifically the possible lower bound of the differential energy flux of electron precipitation at 100 eV, from a 630‐nm auroral image obtained with a ground‐based all‐sky imager.

Debye‐Scale Bipolar Structures and Their Role in the Electron Trajectory Instability at the Bow Shock

Journal of Geophysical Research: Space Physics, Volume 131, Issue 1, January 2026.
Abstract A number of mechanisms have been suggested to operate within the terrestrial bow shock to redistribute energy contained in the incoming solar wind flow. The majority of mechanisms involve the generation of turbulence while some are based on particle motion alone.

The High Plasma Density Observed Along the PJ57 Juno Flyby of Io Implies the Presence of a Dense Atomic Corona

Journal of Geophysical Research: Space Physics, Volume 131, Issue 1, January 2026.
Abstract On December 2023, the Juno spacecraft made a flyby of Io above the northern hemisphere at a closest approach (CA) altitude of ∼1,500 km (PJ57). The Juno/Waves and Radio‐occultation measurements showed a surprising large electron density ∼28,000 cm−3 near closest approach.

The Origin of Non‐Gyrotropic Distribution Functions in Compressed Current Sheets

Journal of Geophysical Research: Space Physics, Volume 131, Issue 1, January 2026.
Abstract Non‐gyrotropic distribution functions are often observed in thin current sheets prior to magnetic reconnection. This study uses NASA's Magnetospheric Multiscale mission data to confirm a novel source of agyrotropy in compressed current sheets and highlights its significance in reconnection.
