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

On the Escape of Low-frequency Waves from Magnetospheres of Neutron Stars
The Astrophysical Journal, 2023 We study the nonlinear decay of the fast magnetosonic (fms) into the Alfvén waves in relativistic force-free magnetohydrodynamics. The work has been motivated by models of pulsar radio emission and fast radio bursts (FRBs), in which the emission is ...

Journal of Geophysical Research: Space Physics, Volume 131, Issue 10, October 2026.Abstract This study presents a high‐resolution three‐dimensional global magnetohydrodynamic (MHD) simulation of the historic geomagnetic storm of 10–11 May 2024, using observational data for the ACE solar wind input. This extreme event was characterized by intense solar wind dynamic pressure (∼50 nPa) and exceptionally strong interplanetary magnetic ...

Earthward O+ Injections in the Plasma Sheet Boundary Layer During Geomagnetic Storms
Journal of Geophysical Research: Space Physics, Volume 131, Issue 10, October 2026.Abstract During geomagnetic storms, energetic ions are injected from the Earth's magnetotail along the plasma sheet boundary layer (PSBL). Owing to its off‐equatorial inclined orbit, the Arase satellite is in a prime position to observe these injections in the PSBL on the nightside at the apogee.

Journal of Geophysical Research: Space Physics, Volume 131, Issue 10, October 2026.Abstract Ultra‐low frequency (ULF) waves with frequencies 10–140 s are a characteristic feature of the foreshock, playing important roles in transient formation, shock reformation, and particle acceleration. We utilize 23 years of Cluster data to map ULF wave power and compressibility in the vicinity of Earth's bow shock, combining Cluster data with ...

Stellar winds driven by Alfven waves [PDF]
, 1973 Models of stellar winds were considered in which the dynamic expansion of a corona is driven by Alfven waves propagating outward along radial magnetic field lines.

Journal of Geophysical Research: Space Physics, Volume 131, Issue 10, October 2026.Abstract We study the development of the Kelvin‐Helmholtz instability (KHI) along the dusk dayside Earth's magnetopause with and without the presence of enhanced plasma density at the shear interface. Using three‐dimensional MAGE global simulations, we establish general KHI growth rate diagrams, which depend sensitively on the transverse profiles of ...

ELECTROSTATIC CONVECTIVE CELL AND ALFVEN WAVES
, 1991 A derivation leading to the dispersion relation for the electrostatic convective cell has been extended to electromagnetic fluctuations. As a result, the dispersion relations for Alfven waves with the damping rates similar to that of the convective cell ...

Journal of Geophysical Research: Space Physics, Volume 131, Issue 10, October 2026.Abstract The April 2023 geomagnetic storm significantly impacted the thermosphere‐ionosphere system, particularly over South America and midlatitude regions. This study analyzes ground‐based geomagnetic and ionospheric data, alongside Swarm satellite measurements, to investigate the physical mechanisms driven by intense solar wind energy input ...

Propagation Dynamics of Fast Electron Beam and Its Electron Cyclotron Maser Emission
Journal of Geophysical Research: Space Physics, Volume 131, Issue 10, October 2026.Abstract Fast electron beams (FEBs) and coherent radio bursts both are very common plasma activity phenomena in the cosmos. The electron cyclotron maser (ECM) instability driven by FEBs trapped in magnetic fields can directly amplify radio wave radiations.
