Guiding of whistler-mode waves with frequencies above one half of the gyrofrequency in the magnetosphere [PDF]

Serbian Astronomical Journal, 1999
Ray-tracing calculations show that a trough, L = 4.6, located in the region outside the plasmapause is capable to guide whistler-mode waves in frequency range 0.5fBmin−0.64fBmin, from one hemisphere to the other.

Saturn's Plasmapause: Signature of Magnetospheric Dynamics [PDF]

Journal of Geophysical Research: Space Physics, 2019
AbstractWe explore the paradigm that Saturn's plasmapause marks the boundary between the magnetic flux tubes that have been circulating around the planet for some time, accumulating a dense load of Enceladus‐sourced material, and those that have recently undergone tail reconnection, shedding the bulk of the cold plasma and retaining a more tenuous ...

“Caterpillar” ULF Waves in the Dusk Side Sub‐Auroral Region: Conjugate Observations With SuperDARN, Arase and Ground Magnetometers

Journal of Geophysical Research: Space Physics, Volume 131, Issue 5, May 2026.
Abstract On 23 November 2022, during exceptionally quiet geomagnetic conditions, a distinct ultra‐low frequency (ULF) wave in the Pc5 band (∼2.4 mHz) was observed in the duskside sub‐auroral region by two Canadian SuperDARN (Super Dual Auroral Radar Network) radars.

Modeling the Leakage of Hiss Waves From the Plasmasphere

Journal of Geophysical Research: Space Physics, Volume 131, Issue 5, May 2026.
Abstract Plasmaspheric hiss waves can cross the plasmasphere boundary layer (PBL) and leak into the plasmatrough, serving as the main source of exohiss waves. However, it remains unclear how the PBL and wave characteristics affect the leakage process of hiss waves. In this study, we conducted a detailed parametric ray tracing study to model the leakage

Analysis of Chorus Wave Power on Burst‐Mode Timescales During the Van Allen Probes Era

Journal of Geophysical Research: Space Physics, Volume 131, Issue 5, May 2026.
Abstract Interactions between whistler‐mode chorus waves and electrons are a key driver of dynamics in Earth's radiation belts. These global dynamics are often described using Fokker‐Planck diffusion models. Whilst, in many cases, such models effectively describe the large scale changes within the region, they often rely upon spatially and temporally ...

Theory and Modeling of Large Scale Plasmapause Surface Waves [PDF]

The plasmapause in Earth's magnetosphere represents the boundary between the plasma which co-rotates with the Earth (plasmasphere), and the more tenuous plasmatrough outside.

Multi-satellite study of the excitation of Pc3 and Pc4-5 ULF waves and their penetration across the plasmapause during the 2003 Halloween superstorm [PDF]

Annales Geophysicae, 2015
We use multi-satellite and ground-based magnetic data to investigate the concurrent characteristics of Pc3 (22–100 mHz) and Pc4-5 (1–22 mHz) ultra-low-frequency (ULF) waves on the 31 October 2003 during the Halloween magnetic superstorm. ULF waves are

On the North‐South Symmetry of the Chorus Source Region: Conjugate Observations by the Cluster Spacecraft

Journal of Geophysical Research: Space Physics, Volume 131, Issue 5, May 2026.
Abstract Chorus waves are arguably the most important electromagnetic emissions in the Earth's magnetosphere, being responsible for both energization and loss of radiation belt electrons. Chorus generation, inherently related to nonlinear wave‐particle interactions, as well as the frequency‐time shapes of individual elements forming it, are not yet ...

A new plasmapause model based on IMAGE RPI and Van-Allen-Probe data via automatic detection [PDF]

, 2023
The plasmapause, i.e. the outer boundary of the plasmasphere, is characterised by a sharp electron density gradient. The Neustrelitz ESOC PlasmaPause Model (NEPPM) is a newly developed model of the plasmapause location Lpp.
