Nonlinear theory of non-axisymmetric resonant slow waves in straight magnetic flux tubes [PDF]
, 2000 Nonlinear resonant slow magnetohydrodynamic (MHD) waves are studied in weakly dissipative isotropic plasmas for a cylindrical equilibrium model. The equilibrium magnetic field lines are unidirectional and parallel with the z axis. The nonlinear governing

The Effect of Steady Flow on the Physical Quantities of Slow mMagneto Acoustic Waves in Solar Coronal Plasma [PDF]
Iranian Journal of Astronomy and Astrophysics, 2020 textbf{Damping of slow magnetohydrodynamic(MHD) waves and oscillations are believed to contribute to the heating of the solar corona. Since the launch of solar space telescopes, many observational evidences for the occurrence of slow MHD waves have been ...

MHD wave modes resolved in fine-scale chromospheric magnetic structures [PDF]
, 2015 Within the last decade, due to significant improvements in the spatial and temporal resolution of chromospheric data, magnetohydrodynamic (MHD) wave studies in this fascinating region of the Sun's atmosphere have risen to the forefront of solar physics ...

The Astrophysical Journal, 2023 Braginskii magnetohydrodynamics (MHD) provides a more accurate description of many plasma environments than classical MHD since it actively treats the stress tensor using a closure derived from physical principles.

Simulation of radiation belt wave-particle interactions in an MHD-particle framework
Frontiers in Astronomy and Space Sciences, 2023 In this paper we describe K2, a comprehensive simulation model of Earth’s radiation belts that includes a wide range of relevant physical processes. Global MHD simulations are combined with guiding-center test-particle methods to model interactions with ...

Coronal heating by MHD waves [PDF]
Astronomy & Astrophysics, 2006 Aims. We study the possible role of magnetohydrodynamic (MHD) waves in the heating of solar corona and magnetic coronal loops. Methods. Taking into account viscosity and thermal conductivity, we obtained a general fifth order dispersion relation for MHD waves propagating in a homogeneous, magnetically structured, compressible low-β plasma.

Dynamics of nonlinear resonant slow MHD waves in twisted flux tubes [PDF]
Nonlinear Processes in Geophysics, 2002 Nonlinear resonant magnetohydrodynamic (MHD) waves are studied in weakly dissipative isotropic plasmas in cylindrical geometry. This geometry is suitable and is needed when one intends to study resonant MHD waves in magnetic flux tubes (e.g.

Effect of partial ionization on wave propagation in solar magnetic flux tubes [PDF]
, 2013 Observations show that waves are ubiquitous in the solar atmosphere and may play an important role for plasma heating. The study of waves in the solar corona is usually based on linear ideal magnetohydrodynamics (MHD) for a fully ionized plasma. However,

On wave turbulence in MHD [PDF]
Nonlinear Processes in Geophysics, 2001 We describe the fundamental differences between weak (wave) turbulence in incompressible and weakly compressible MHD at the level of three-wave interactions. The main difference is in the structure of the resonant manifolds and the mechanisms of redistribution of spectral densities along the applied magnetic field B0. Similar to pure acoustic waves, a
