Abstract

It is proved in the surface potential waves approximation that not oniy a bounded plasma with flows along the magnetostatic field, but also a plasma with a finite ‘longitudinal temperature’ of the electrons can be unstable against axially asymmetric perturbations of magnetohydrodynamic type. The branches of surface oscillations of a cold plasma, and the conditions for their excitation by an admixture of electrons with a sufficiently high ‘longitudinal temperature’ in various geometrical configurations, are also derived in the aper.
