Force-free Wave Interaction in Magnetar Magnetospheres: Computational Modeling in Axisymmetry
The Astrophysical JournalCrustal quakes of highly magnetized neutron stars can disrupt their magnetospheres, triggering energetic phenomena like X-ray and fast radio bursts. Understanding plasma wave dynamics in these extreme environments is vital for predicting energy transport

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.

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.

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 ...

Propagating transverse waves in soft X-ray coronal jets [PDF]
, 2009 Aims. The theoretical model for magnetohydrodynamic (MHD) modes guided by a field-aligned plasma cylinder with a steady flow is adapted to interpret transverse waves observed in solar coronal hot jets, discovered with Hinode/XRT in terms of fast ...

Alfvén Wave Conversion and Reflection in the Solar Chromosphere and Transition Region
Physics, 2022 Series solutions are used to explore the mode conversion of slow, Alfvén and fast magnetohydrodynamic waves injected at the base of a two-isothermal-layer stratified atmosphere with a uniform magnetic field, crudely representing the solar chromosphere ...

The Uniturbulence and Alfvén Wave Solar Model (UAWSoM) in MPI-AMRVAC
Astronomy & AstrophysicsContext. 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 ...

A magnetic thrust action on small bodies orbiting a pulsar [PDF]
, 2011 We investigate the electromagnetic interaction of a relativistic stellar wind with small bodies in orbit around the star. Based on our work on the theory of Alfv\'en wings to relativistic winds presented in a companion paper, we estimate the force ...

Velocity Field of Compressible MHD Turbulence: Wavelet Decomposition and Mode Scalings
, 2010 We study compressible MHD turbulence, which holds key to many astrophysical processes, including star formation and cosmic ray propagation. To account for the variations of the magnetic field in the strongly turbulent fluid we use wavelet decomposition ...
