Nonlinear Proton Dynamics in the Formation of Rising‐Tone EMIC Wave Subpackets

Geophysical Research Letters, Volume 52, Issue 11, 16 June 2025.
Abstract Electromagnetic ion cyclotron (EMIC) waves are commonly observed in the Earth's magnetosphere and play a significant role in regulating relativistic electron fluxes. The waveform of EMIC waves comprises amplitude‐modulated wave packets, known as “subpackets.” Despite their prevalence, the underlying physics and associated particle dynamics for

Control of the Jovian Magnetopause by Iogenic Plasma: Initial Results From Global MHD Simulations

Geophysical Research Letters
The size and variability of Jupiter's magnetosphere are not only determined by upstream conditions but also substantially influenced by internal processes within Jupiter's magnetosphere, specifically the dynamics of the rotation magnetodisc.

A Long‐Term Survey of the Role of Atmospheric Planetary Waves in the Day‐to‐Day Variability of the Ionosphere

Journal of Geophysical Research: Space Physics, Volume 130, Issue 6, June 2025.
Abstract Atmospheric planetary waves play an important role in shaping how the ionosphere is coupled to the rest of the Earth's atmosphere. Of significant interest in this study are the 2‐, 3‐, and 6‐day planetary waves. Using multiple long‐term datasets, we performed an extensive survey of these wave events in the atmosphere and ionosphere.

Statistical Observations in Support of Bow Shock Current Closure to Earth's High‐Latitude Ionosphere During Non‐Zero IMF By

Journal of Geophysical Research: Space Physics, Volume 130, Issue 6, June 2025.
Abstract The bow shock current (BSC) plays an important role in supplying the magnetosphere with solar wind energy, in particular during times of low solar wind magnetosonic Mach numbers. Since the magnetic pile‐up in the magnetosheath has to be maintained, the BSC cannot close locally, but must instead connect to magnetospheric current systems ...

Two-Stream Instability as a Mechanism for Toroidal Magnetic Field Generation in the Magnetosphere of Crab Pulsar [PDF]

arXiv, 2011
New plasma mechanism for the generation of toroidal magnetic field in the magnetosphere of Crab pulsar is presented. It is based on the development of two-stream instability in the relativistic electron-positron plasma of the pulsar magnetosphere. In particular, pulsar magnetosphere relativistic plasma is penetrated by ultrarelativistic electron beam ...

Gamma-Ray Light Curves from Pulsar Magnetospheres with Finite Conductivity [PDF]

, 2012
We investigate the shapes of \gamma-ray pulsar light curves using 3D pulsar magnetosphere models of finite conductivity. These models, covering the entire spectrum of solutions between vacuum and force-free magnetospheres, for the first time afford mapping the GeV emission of more realistic, dissipative pulsar magnetospheres.

A Kp‐Driven Machine Learning Model Predicting the Ultraviolet Emission Auroral Oval

Journal of Geophysical Research: Machine Learning and Computation, Volume 2, Issue 2, June 2025.
Abstract Auroras can intuitively reflect the energy coupling between the Sun and the Earth and are an excellent indicator for monitoring and predicting space weather effects. Establishing an auroral oval model driven by the geomagnetic index, predicted up to 3 days ahead, can effectively assess energy transfer in space.

Global current circuit structure in a resistive pulsar magnetosphere model [PDF]

, 2017
Pulsar magnetospheres have strong magnetic fields and large amounts of plasma. The structures of these magnetospheres are studied using force-free electrodynamics. To understand pulsar magnetospheres, discussions must include their outer region. However, force-free electrodynamics is limited in it does not handle dissipation.
