Electrodynamics of Pulsar Magnetospheres [PDF]

open access: yesSymposium - International Astronomical Union, 2004
I review the theoretical understanding of the global structure of pulsar magnetospheres concentrating on recent progress in force-free electrodynamics and first-principles simulations of magnetospheres.

Three‐Dimensional Anisotropy of Turbulence at Ion‐Scales in the Magnetotail's Bursty Bulk Flow

open access: yesGeophysical Research Letters, Volume 52, Issue 19, 16 October 2025.
Abstract Using the data from Magnetospheric Multiscale mission, we statistically investigate the anisotropy of turbulence within bursty bulk flows (BBFs) in the Earth's magnetotail. By computing five‐point second‐order structure functions, we reveal the three‐dimensional anisotropy and scaling properties of turbulence at ion scales.

Recent advances in the magnetic reconnection, dipolarization, and auroral processes at giant planets from the perspective of comparative planetology

open access: yesEarth and Planetary Physics
Magnetic reconnection and dipolarization are crucial processes driving magnetospheric dynamics, including particle energization, mass circulation, and auroral processes, among others.

Whistler Chorus Amplification in the Magnetosphere: The Nonlinear Free‐Electron Laser Model and the Ginzburg‐Landau Equation

open access: yesGeophysical Research Letters, Volume 52, Issue 19, 16 October 2025.
Abstract We present a novel nonlinear model for whistler‐mode chorus amplification based on the free‐electron laser (FEL) mechanism. First, we derive the nonlinear collective variable equations for the whistler‐electron interaction. Consistent with in situ satellite observations, these equations predict that a small seed wave can undergo exponential ...

Magnetic Field and Plasma Asymmetries Between the Martian Quasi‐Perpendicular and Quasi‐Parallel Magnetosheaths

open access: yesGeophysical Research Letters, Volume 52, Issue 19, 16 October 2025.
Abstract The Martian magnetosheath acts as a conduit for mass and energy transfer between the upstream solar wind and its induced magnetosphere. However, our understanding of its global properties remains limited. Using 9 years of data from NASA's Mars Atmosphere and Volatile EvolutioN mission, we performed a quantitative statistical analysis to ...

The role of the dynamic terrestrial exosphere in the storm-time ring current decay

open access: yesFrontiers in Astronomy and Space Sciences
The charge exchange interaction between exospheric hydrogen (H) atoms and energetic ions in the terrestrial ring current is a crucial mechanism for dissipating global magnetospheric energy, especially during the recovery phase of geomagnetic storms ...
