Large-amplitude electromagnetic waves in magnetized relativistic plasmas with temperature [PDF]
Nonlinear Processes in Geophysics, 2014 Propagation of large-amplitude waves in plasmas is subject to several sources of nonlinearity due to relativistic effects, either when particle quiver velocities in the wave field are large, or when thermal velocities are large due to relativistic ...

Review Article: MHD Wave propagation near coronal null points of magnetic fields [PDF]
, 2011 We present a comprehensive review of MHD wave behaviour in the neighbourhood of coronal null points: locations where the magnetic field, and hence the local Alfvén speed, is zero. The behaviour of all three MHD wave modes, i.e.

Energy exchange and wave action conservation for magnetohydrodynamic (MHD) waves in a general, slowly varying medium [PDF]
Annales Geophysicae, 2014 Magnetohydrodynamic (MHD) waves in the solar wind and magnetosphere are propagated in a medium whose velocity is comparable to or greater than the wave velocity and which varies in both space and time. In the approximation where the scales of the time

Definition of the Alfvén mode in inhomogeneous magnetic field
Solar-Terrestrial Physics, 2023 The article is methodological and defines the concept of the linear Alfvén mode. There are two definitions — electrodynamic and hydrodynamic. In the former, the Alfvén mode is considered a wave with a potential transverse electric field.

Alfvén ship waves: high-m ULF pulsations in the magnetosphere generated by a moving plasma inhomogeneity [PDF]
Annales Geophysicae, 2008 The generation of a high-m Alfvén wave by substorm injected energetic particles in the magnetosphere is studied. The wave is supposed to be emitted by an alternating current created by the drifting particle cloud or ring current inhomogeneity.

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.Abstract Mars directly interacts with the solar wind and hosts a complex plasma‐wave environment. Using MAVEN observations, we identify an event in the dusk‐side Martian magnetosheath where strongly compressive sub‐cyclotron kinetic‐scale fluctuations coexist with second‐harmonic proton cyclotron waves (PCWs).

Solar-Terrestrial Physics, 2022 In this paper, we examine a torsional Alfvén wave produced by periodic plasma bunches in a magnetized plasma flux tube. A new effect has been revealed: the wave is generated not only during the action of bunches, but also for a long time after the ...

Evolution of Magnetospheric Boundary Layers Under the 10 May 2024 ICME Impact
Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.Abstract On 10 May 2024, an interplanetary coronal mass ejection‐driven shock impacted the dayside magnetopause, compressing it to ∼5 RE. A northward interplanetary magnetic field suppressed dayside reconnection and allowed a clear investigation of the magnetosphere response.

Kink oscillations in magnetic tubes with twisted annulus [PDF]
, 2008 Aims.We study kink waves in a magnetic flux tube modelled as a straight core surrounded by a magnetically twisted annulus, both embedded in a straight ambient external field, and derive the dispersion relation for this configuration.
