Periodicities in Saturn's magnetosphere

, 2013
Although the exact rotation period of Saturn is unknown, Saturn's magnetosphere displays an abundance of periodicities near ~10.7 h. Such modulations appear in charged particles, magnetic fields, energetic neutral atoms, radio emissions, motions of the ...

High‐Speed Electron Flows in the Earth Magnetotail

AGU Advances, Volume 6, Issue 2, April 2025.
Abstract High‐speed electron flows (HSEFs) play a crucial role in the energy dissipation and conversion processes within the terrestrial magnetosphere and can drive various types of plasma waves and instabilities, affecting the electron‐scale dynamics.

In Situ Calculation of Spaceflight Magnetometer Coupling Coefficients for Interference Removal Using the Reduction Algorithm for Magnetometer Electromagnetic Noise (RAMEN)

Earth and Space Science, Volume 12, Issue 4, April 2025.
Abstract Space‐based in situ magnetic field measurements are often limited by spacecraft‐generated interference, known as stray magnetic fields. These fields, generated by currents from spacecraft subsystems, are frequently several times stronger than the ambient magnetic field signals of interest.

Automatic Identification of Past Radiation Belts Electron Enhancement Events Using a Ground‐Based Parameter

Earth and Space Science, Volume 12, Issue 4, April 2025.
Abstract We propose a new method for automatically identifying radiation belt electron enhancement events using Ca, a ground‐based 1D surrogate index for the global dynamics of the electron radiation belts. Our method improves event identification by accurately determining start and end dates, considering intensification and return‐to‐equilibrium ...

Electron Phase Space Densities in Geostationary Orbits as Measured With GK2A, GOES‐16, and GOES‐17 Satellites

Journal of Geophysical Research: Space Physics, Volume 130, Issue 4, April 2025.
Abstract This study investigated electron phase space densities (PSDs) in geostationary orbits using data from Korea's geostationary satellite, GK2A, as well as GOES‐16 and GOES‐17 satellites. The PSDs were computed from electron fluxes measured by each satellite during a geomagnetically quiet period as defined by stringent conditions on geomagnetic ...

Magnetospheric Dynamics and Chaos Theory [PDF]

arXiv, 2012
The results of this study were announced and published in Greek in the Fifth Panhellenic Conference Proceedings of the Hellenic Physical Society. It is the sequel of a previous study (Pavlos, 1988), in which it was introduced the hypothesis of magnetospheric chaos for the interpretation of magnetic substorms.

Relativistic theory of wave‐particle resonant diffusion with application to electron acceleration in the magnetosphere

, 1998
Resonant diffusion curves for electron cyclotron resonance with field-aligned electromagnetic R mode and L mode electromagnetic ion cyclotron (EMIC) waves are constructed using a fully relativistic treatment. Analytical solutions are derived for the case
