Exact Nonlinear Decomposition of Ideal-MHD Waves Using Eigenenergies II: Fully Analytical EEDM Equations and Pseudo-Advective Energies
Abbas Raboonik, David Pontin, Lucas Tarr
Physical insight into plasma evolution in the magnetohydrodynamic (MHD) limit can be revealed by decomposing the evolution according to the characteristic modes of the system. In t…
