Electromagnetic oscillations of the Earth's upper atmosphere (review) [PDF]
Annales Geophysicae, 2010 A complete theory of low-frequency MHD oscillations of the Earth's weakly ionized ionosphere is formulated. Peculiarities of excitation and propagation of electromagnetic acoustic-gravity, MHD and planetary waves are considered in the Earth's ...

The Exact Solution of the Riemann Problem in Relativistic MHD [PDF]
, 2006 We discuss the procedure for the exact solution of the Riemann problem in special relativistic magnetohydrodynamics (MHD). We consider both initial states leading to a set of only three waves analogous to the ones in relativistic hydrodynamics, as well ...

Ducted compressional waves in the magnetosphere in the double-polytropic approximation [PDF]
Annales Geophysicae, 2002 Small-amplitude compressional magnetohydrodynamic-type waves are studied in the magnetosphere. The magnetosphere is treated as a rarefied plasma with anisotropy in the kinetic pressure distribution.

Cosmic ray fluctuations and MHD waves in the solar wind
Solar-Terrestrial Physics, 2023 During large-scale solar wind disturbances, variations in galactic cosmic rays with periods from several minutes to 2–3 hours, which are called cosmic ray fluctuations in the scientific literature, often occur.

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.

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 ...

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.

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 ...

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.
