Spatial Scales of Electron Density Fluctuations in the Martian Ionosphere
The Astrophysical JournalIn recent Martian ionospheric studies, the spatial scales of electron density irregularities have been computed using magnetic field measurements by treating these fluctuations as electromagnetic.

Generation of Falling‐Tone Whistler‐Mode Chorus Waves in the Earth's Magnetosphere
Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.Abstract Chorus waves are intense whistler‐mode emissions in space that play a key role in regulating energetic electron dynamics in the hazardous radiation belt. While rising‐tone chorus has been extensively studied, the generation mechanism of falling‐tone chorus remains a long‐standing problem.

Power Spectral Characteristics of Martian Ionospheric Irregularities
The Astrophysical JournalThe intrinsic magnetic field of a planet plays a key role in its ionospheric dynamics. Mars lacks a global magnetic field, thus ionospheric plasma is weakly coupled to crustal and induced magnetic field.

Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.Abstract Discrete energy bands of ion fluxes, typically organized in velocity with equal separations, have been frequently observed in Jupiter's magnetosphere either in association with Galilean moons or in regions far from their influence. Here, we focus on the latter type and propose that these bands are manifestations of bounce‐phase structuring ...

An Estimate of the Importance of Electron-stimulated Desorption of Sodium at Mercury
The Planetary Science JournalWe revisit the importance of electron-stimulated Desorption (ESD) as a source of neutral sodium (Na) atoms and Na ^+ ions in Mercury’s exosphere and ionosphere.

Journal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.Abstract We present a case study of large amplitude, compressional Pc5 waves observed by GOES 13 and 15 at geosynchronous orbit near noon. These waves were excited near the arrival time of two consecutive solar wind dynamic pressure spikes at the magnetopause, the second of which was associated with a large and rapid southward turning of the ...

AGU Advances, Volume 7, Issue 4, August 2026.Abstract Wave‐particle resonance is a key mechanism for energy transfer in collisionless plasmas with important implications for wave excitation and particle acceleration. Cyclotron resonance occurs when a particle's gyromotion synchronizes with the wave fields, with their interactions usually describable by quasilinear diffusion or nonlinear trapping.

The Colocation of Magnetic Reconnection and Current Disruption in Jovian Middle Magnetosphere
The Astrophysical Journal LettersMagnetic reconnection and current disruption are two key processes in driving energy conversion and dissipation in planetary magnetospheres. At the Earth, the two processes usually occur at different locations: the current disruption process occurs more ...

The Influence of Surface Binding Energy on Sputtering in Models of the Sodium Exosphere of Mercury
The Planetary Science Journal, 2022 We have simulated the sodium (Na) exosphere of Mercury to show how the exosphere is affected by the assumed surface binding energy (SBE) of Na in the sputtered component.
