Alfvén wave evolution into magnetic filaments in 3-D space plasma

Earth, Planets and Space, 2020
Nonlinearities in space and astrophysical plasmas generate a set of magnetic filaments or bundles that have an incompressible sense of fluctuations and propagate highly obliquely to the mean magnetic field.

Exploring Jupiter's Mid‐Latitude Dusk Magnetopause: The Impact of Magnetic Reconnection

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract The Juno mission has elucidated magnetosphere processes, structure, and dynamics via multi‐instrument plasma and magnetic field observations. In this study, these instruments are used to identify magnetic reconnection during the Juno extended mission from a survey of 490 magnetopause crossings at the mid‐latitude southern dusk magnetopause ...

Linear Alfvén waves in the solar atmosphere

, 2010
Aims. We aim to analytically and numerically explore small-amplitude Alfvén waves in the solar atmosphere. Methods. We transform the wave equations to obtain the cutoff-frequency and wave travel time for strictly linear Alfvén waves.

Parallel electric fields in dispersive shear Alfvén waves in the dipolar magnetosphere [PDF]

, 1999
Existing theories do not explain large parallel electric fields that are associated with keV electron precipitation in auroral arcs. The MHD electron response results in an electrical conductivity in the low altitude magnetosphere that is two orders of ...

The Effect of the Parametric Decay Instability on the Morphology of Coronal Type III Radio Bursts

The Astrophysical Journal Letters, 2023
The nonlinear evolution of Alfvén waves in the solar corona leads to the generation of Alfvénic turbulence. This description of the Alfvén waves involves parametric instabilities where the parent wave decays into slow mode waves giving rise to density ...

Convective Amplification of Ionospheric Feedback by a Finite‐Duration Inertial Alfvén‐Wave Source

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract We investigate the ionospheric feedback instability (IFI) driven by a finite‐duration localized source of inertial Alfvén waves. Wave‐excited conductance perturbations undergo Pedersen mobility drift in the convection and wave electric fields and are amplified.

Clockwise and counter clockwise 6 & 9 year geostrophic MC (& Rossby) waves in centre of the mechanism of geomagnetic jerks and relevant LODs

Contributions to Geophysics and Geodesy, 2022
Versus the theory of fully stochastically mechanism of geomagnetic jerks based on the buoyant force driven Quasi-Geostrophic (QG) dynamo, the torsional waves in realistic condition of the Earth's core evolve in the intradecadal time scales.

Cross‐Scale Energy Transfer at Dipolarization Front in the Earth's Magnetotail

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract Dipolarization front (DF) is a key structure for energy conversion and transport in planetary magnetotails. Although multiscale processes have been observed around DFs, quantitative analyses of cross‐scale coupling remain lacking. Here, we calculate cross‐scale transfer rate for different energy channels at a DF using Magnetospheric Multiscale

Coronal Loop Heating By Discrete Alfvén Waves

, 2015
We have modeled the solar coronal active loop heating by discrete Alfvén waves. Discrete Alfvén waves (DAW) are a new class of Alfvén waves which can be described by the two-fluid model with finite ion-cyclotron frequency, or the MHD model with plasma ...

The Uniturbulence and Alfvén Wave Solar Model (UAWSoM) in MPI-AMRVAC

Astronomy & Astrophysics
Context. The coronal heating problem and the generation of the solar wind remain fundamental challenges in solar physics. While approaches based on, e.g., the Alfvén Wave Solar Model (AWSoM) have proven highly successful in reproducing the large-scale ...
