Energy-Casimir, dynamically accessible, and Lagrangian stability of extended magnetohydrodynamic equilibria
D. A. Kaltsas, G. N. Throumoulopoulos, P. J. Morrison
The formal stability analysis of Eulerian extended magnetohydrodynamics (XMHD) equilibria is considered within the noncanonical Hamiltonian framework by means of the energy-Casimir…

Ellipticity conditions for the extended MHD Grad-Shafranov-Bernoulli equilibrium equations
D. A. Kaltsas, G. N. Throumoulopoulos, P. J. Morrison
In this study, we find the points of transition between elliptic and hyperbolic regimes for the axisymmetric extended magnetohydrodynamic (MHD) equilibrium equations. The elliptici…
