Chorus Wave‐Induced Ionospheric Variability

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Electron microbursts are short‐lived but intense electron precipitation and constitute a significant source of electron losses into the ionosphere and lower atmosphere. They are primarily produced by wave‐particle interaction with chorus waves in the magnetosphere.

Revealing the Formation of the <20 MeV Inner Proton Radiation Belt at L ∼ 2 During the 10–11 May 2024 Superstorm

Geophysical Research Letters
A new proton radiation belt was identified during the geomagnetic superstorm of 10–11 May 2024. To investigate its origin, we use an MHD‐test particle simulation to model solar energetic proton (SEP) trapping and the evolution of the initial trapped ...

Trapped antiprotons in the Earth inner radiation belt in PAMELA experiment

, 2011
The existence of trapped antiprotons in the Earth's inner radiation belt has been theoretically predicted, but not observed. We present a procedure for antiproton selection and the observation results from the PAMELA space experiment measurements.

Chorus Element Repetition: Roles of Energetic Electron Injection and Nonlinear Wave Growth

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Chorus waves are coherent whistler‐mode emissions in Earth’s magnetosphere and play a key role in the acceleration and loss of radiation belt electrons. Their spectra commonly consist of discrete and repetitive elements, yet the mechanism governing this repetition is not fully understood.

Archimedean Spiral Distribution of Energetic Particles in Earth's Inner Radiation Belt

Geophysical Research Letters
Archimedean spirals are common in various fields such as biology, engineering, astronomy, and space physics. Here we report the discovery of patterns resembling the general Archimedean spirals in particle distributions in the Earth radiation belt.

VLF waves from ground‐based transmitters observed by the Van Allen Probes: Statistical model and effects on plasmaspheric electrons

Geophysical Research Letters, 2017
Whistler mode very low frequency (VLF) waves from powerful ground‐based transmitters can resonantly scatter energetic plasmaspheric electrons and precipitate them into the atmosphere.

New Electron Population Trapped at Low Latitudes Near Jupiter

Geophysical Research Letters, Volume 53, Issue 17, 16 September 2026.
Abstract We report observations of a low energy (<2 keV), trapped electron population near Jupiter's magnetic equator made by the Jovian Auroral Distributions Experiment (JADE) on Juno. Electron intensity peaks around the location of the minimum magnetic field magnitude along the field line that is connected to Juno.

Evidence for Random Walk Transport of Small Asteroids from the Main Belt to the Inner Solar System

The Planetary Science Journal
The transport of some main-belt asteroids to the inner solar system depends on Yarkovsky radiation forces changing the orbits of those asteroids. However, these forces depend on the rotational states of the asteroids, and YORP radiation forces act to ...

Sub‐MeV Electron Precipitation Driven by EMIC Waves: New Insights From CIRBE/REPTile‐2 Measurements

Geophysical Research Letters
Electromagnetic ion cyclotron (EMIC) waves are recognized as a key driver of relativistic (>1 MeV) electron loss in Earth's magnetosphere. Growing evidence also suggests that EMIC wave can efficiently scatter sub‐MeV electrons, although the precise ...

Relativistic proton fluxes observed by Van Allen Probes in the inner radiation belt during solar proton events

, 2018
On August of 2012, Van Allen Probes (VAP), also known as Radiation Belt Storm Probes (RBSP) were launched to explore the Earth’s radiation belts which are located in the inner magnetosphere. Since the Relativistic Proton Spectrometer (RPS) carried by VAP
