Recent Advancements and Remaining Challenges Associated With Inner Magnetosphere Cross‐Energy/Population Interactions (IMCEPI)

open access: yesJournal of Geophysical Research: Space Physics, 2019
The geospace inner magnetosphere, within about 10 Earth radii, contains various plasma populations with energy from a few electron volts to megaelectron volts and plays important roles in regulating the energy density of the magnetosphere, the magnetic ...

First Results of a New Inversion Tool for Thermospheric Neutral Mass Density Computations During Severe Geomagnetic Storms

open access: yesAGU Advances, Volume 7, Issue 3, June 2026.
Abstract In Low Earth Orbit (LEO), atmospheric drag is the dominant source of trajectory prediction error below approximately 700 km altitude, primarily due to inaccuracies in thermospheric density models. This work presents a method for temporally deconvolving Energy Dissipation Rates (EDRs) to produce single‐satellite density estimates, which can be ...

Latitudinal dependence of ground VLF transmitter wave power in the inner magnetosphere

open access: yesFrontiers in Astronomy and Space Sciences, 2023
In this study, we use approximately 3 years of observations from the Exploration of energization and Radiation in Geospace (ERG/Arase) satellite to statistically study the meridional distribution of wave power from very-low-frequency (VLF) ground ...

On high brightness temperature of pulsar giant pulses [PDF]

open access: yes, 2015
A wide range of events observed at the giant pulses (high energy density, observed localization of giant pulses (GPs) relative to the average pulse, fine structure of GPs with duration up to some nanoseconds, observed circular polarization of GPs ...

First Observation of Sawtooth‐Like Undulations in Afternoon Detached Auroral Arcs Modulated by Surface Waves at the Plasmaspheric Plume Boundary

open access: yesAGU Advances, Volume 7, Issue 3, June 2026.
Abstract The afternoon detached auroral arc is an important phenomenon in the subauroral region, reflecting coupling processes between the Earth's magnetosphere and ionosphere. Previous studies have not identified fine‐scale structures in such arcs, leaving the dynamics underlying their formation poorly understood.

Anti-particles in the inner magnetosphere: energetic positron population

open access: yesGeofísica Internacional, 1996
Se analiza la generación de antipartículas atrapadas en el cinturón interior de la magnetosfera. Dichas partículas podrían tener flujos en exceso de los flujos interestelares generados por rayos cósmicos.

Electron pitch-angle diffusion: resonant scattering by waves vs. nonadiabatic effects [PDF]

open access: yesAnnales Geophysicae, 2013
In this paper we investigate the electron pitch-angle diffusion coefficients in the night-side inner magnetosphere around the geostationary orbit (L ~ 7) due to magnetic field deformation.

Magnetically Driven Warping, Precession and Resonances in Accretion Disks [PDF]

open access: yes, 1999
The inner region of the accretion disk onto a rotating magnetized central star (neutron star, white dwarf or T Tauri star) is subjected to magnetic torques which induce warping and precession of the disk.

Machine Learning for Local Detection of Separators in Three‐Dimensional Magnetic Fields

open access: yesJournal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 3, June 2026.
Abstract Magnetic reconnection is a major plasma phenomenon occurring in various key environments ranging from the Sun and near‐Earth space to astrophysical plasmas. While magnetic reconnection is relatively well‐understood under two‐dimensional (2D) settings, it remains challenging to characterize in three‐dimensional (3D) magnetic fields.

Multi-spacecraft observation of plasma dipolarization/injection in the inner magnetosphere [PDF]

open access: yesAnnales Geophysicae, 2007
Addressing the origin of the energetic particle injections into the inner magnetosphere, we investigate the 23 February 2004 substorm using a favorable constellation of four Cluster (near perigee), LANL and Geotail spacecraft. Both an energy-dispersed
