Second-order perturbations in Alfvén waves in cold plasma approximation

Solar-Terrestrial Physics, 2019
The second-order amplitude perturbations driven by Alfvén waves are studied. Equations for such second-order perturbations are derived and their solutions are found. The second-order perturbations are shown to be generated by the magnetic pressure of the

Dialogue on the magnetotail

Eos, Transactions American Geophysical Union, 1985
During the International Magnetospheric Study (IMS), a vast data set was acquired which is presently being brought to bear on solving some of the outstanding questions regarding magnetospheric dynamics. The data involve plasma and field parameters measured on satellites both in the magnetosphere and in the interplanetary medium, as well as ground‐based

Quantifying Uncertainty in OMNI Solar Wind Measurements Projected From L1 to the Earth's Bow Shock

Journal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.
Abstract Many routine measurements of the solar wind plasma and interplanetary magnetic field (IMF) are made at the L1 Sun–Earth Lagrange point; therefore, it is helpful to characterize the errors introduced in propagating these measurements to the near‐Earth environment.

IMF B y influence on fast earthward convection flows in the near-lunar magnetotail

Geoscience Letters
This study investigates the effects of non-zero IMF B y on the magnetotail B y and fast earthward ion convection (V ⊥ > 200 km/s, "⊥" indicates perpendicular to the magnetic field) in the near-lunar magnetotail plasma sheet using the plasma parameters ...

Quasi-separatrix layers induced by ballooning instability in the near-Earth magnetotail [PDF]

Annales Geophysicae, 2019
Magnetic reconnection processes in the near-Earth magnetotail can be highly three-dimensional (3-D) in geometry and dynamics, even though the magnetotail configuration itself is nearly two-dimensional due to the symmetry in the dusk–dawn direction.

Coincident ENA and Narrowband Radio Emissions as Diagnostics of Inward Plasma Transport at Saturn

Journal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.
Abstract Saturn's kilometric radiation (SKR) and Energetic Neutral Atom (ENA) emissions are important diagnostics of the planet's magnetospheric dynamics, intensifying during global plasma injections and displaying characteristic planetary periodicity. Related to the SKR emissions are myriametric narrowband radio emissions that typically appear in the ...

Statistical Survey of Cosmic Noise Absorption in Conjunction With Plasma Wave Measurements

Journal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.
Abstract Using a decade of observations from the Canadian Geospace Observatory Riometer Network (GO‐RIO), we selected an east‐west subset of stations near L∼7 $L\sim 7$ to classify cosmic noise absorption (CNA) (a proxy for enhanced D‐region ionization) into two morphologies, simultaneous and drifting, based on the relative timing of signals across the

On chaotic conductivity in the magnetotail

Geophysical Research Letters, 1992
The concept of chaotic conductivity and the acceleration of particles due to a constant dawn dusk electric field are studied in a magnetotail‐like magnetic field. A test particle simulation is used including the full nonlinear dynamics. It is found that the acceleration process can be understood without invoking chaos and that the cross tail current is

Jovian Auroral Proton Precipitation

Journal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.
Abstract The total power of the Jovian aurora is about 1013–1014 W with ultraviolet emission observed in the Lyman and Werner bands of molecular hydrogen. X‐ray, radio, and infrared emissions have also been observed. The Jovian Auroral Distributions Experiment and the Jovian Energetic Particle Detector Instrument onboard the Juno spacecraft, orbiting ...

Fundamental Poloidal Wave Event Extending From Midnight to Dawn

Journal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.
Abstract Fundamental poloidal (P1) waves are a class of magnetospheric standing Alfvén waves characterized by field line oscillations in the meridional plane. P1 waves are infrequently excited in the ring current region and are believed to be the source of giant pulsations (Pgs) observed on the ground. Pgs are mostly detected on the morning side with a
