A parametric study of the drift-tearing mode using an extended-magnetohydrodynamic model

The linear, collisional, constant-ψ drift-tearing mode is analyzed for different regimes of the plasma-β, ion-skin-depth parameter space with an unreduced, extended-magnetohydrodynamic model. New dispersion relations are found at moderate plasma β and previous drift-tearing results are classified as...

Beschreibung
Zusammenfassung:The linear, collisional, constant-ψ drift-tearing mode is analyzed for different regimes of the plasma-β, ion-skin-depth parameter space with an unreduced, extended-magnetohydrodynamic model. New dispersion relations are found at moderate plasma β and previous drift-tearing results are classified as applicable at small plasma β.
