The classical continuous spectrum of fluid flow found by C.M. Case [Phys. Fluids 3, 143 (1960) ] is contained in the Alfven and slow continua of magnetohydrodynamics (MHD). Contrary to several statements in the literature, most recently by S.N. Bhatt

The equations for the continuous subspectra of the linear magnetohydrodynamic (MHD) normal modes spectrum of two-dimensional (2D) plasmas are derived in general curvilinear coordinates, taking nonadiabatic effects in the energy equation into account.

The magnetohydrodynamic (MHD) spectra of toroidally rotating, axisymmetric tokamaks are analyzed. The continuous spectrum equations for the coupled localized Alfven and slow modes are derived. The effect of flow on this spectrum is threefold: Doppler

Resistive magnetohydrodynamic spectra of toroidal plasmas are calculated using the recently developed Jacobi–Davidson eigenvalue solver. Poloidal mode coupling in finite aspect ratio tokamaks yields gaps in the ideal Alfven continuous spectrum. If

The phase mixing and resonant dissipation of Alfven waves is studied in both the 'closed' magnetic loops and the 'open' coronal holes observed in the hot solar corona. The resulting energy transfer from large to small length scales contributes to the

One of the proposed mechanisms to explain the heating of the solar corona is resonant absorption of magnetic Alfven waves. Numerical studies of this mechanism often involve large scale computations and produce large amounts of data that need to be vi

A systematic study of the spectrum of magnetohydrodynamic (MHD) waves in thermonuclear and astrophysical plasmas is presently undertaken at the FOM Institute for Plasma Physics. This study is based on the fact that the macroscopic waves and instabili

Waves and instabilities of transonically rotating toroidal plasmas present a very complex problem of interest for the two unrelated fields of magnetically‐dominated laboratory plasmas and gravitationally‐dominated astrophysical plasmas. The compl

In transonically rotating toroidal plasmas a new class of local magnetohydrodynamic instabilities is found, called trans-slow Alfven continuum modes, that are due to poloidal flows exceeding the critical slow magnetosonic speed. When this condition i
