Nonlinear MHD Waves in the Solar Wind Plasma Structures
D. Tsiklauri, V. M. Nakariakov, T. D. Arber
We investigate the interaction of magnetohydrodynamic waves with plasma density inhomogeneities. Our numerical study of the full MHD equations shows that: (A) Plasma density inhomo…
Non-resonant nonlinear coupling of magnetohydrodynamic waves in inhomogeneous media
V. M. Nakariakov, D. Tsiklauri, T. D. Arber
A new mechanism for the enhanced generation of compressible fluctuations by Alfven waves is presented. A strongly nonlinear regime of Alfven wave phase-mixing is numerically simula…
A Weakly Nonlinear Alfvenic Pulse in a Transversely Inhomogeneous Medium
D. Tsiklauri, T. D. Arber, V. M. Nakariakov
The interaction of a weakly nonlinear Alfvénic pulse with an Alfvén speed inhomogeneity in the direction perpendicular to the magnetic field is investigated. Identically to the pha…
Wide-Spectrum Slow Magnetoacoustic Waves in Coronal Loops
D. Tsiklauri, V. M. Nakariakov
A model interpreting variations of EUV brightness upward propagating in solar coronal loops as slow magnetoacoustic waves is developed. A loop is considered to have a non-zero plan…
