| Zusammenfassung |
| The stationary inertial Alfvén (StIA) wave (Knudsen, 1996) was predicted for cold, collisionless plasma.
The model was generalized (Finnegan et al., 2008) to include nonzero values of
electron and ion collisional resistivity and thermal pressure. Here, the two-fluid model
is further generalized to include anisotropic thermal pressure. A bounded range of values
of parallel electron drift velocity is found that excludes periodic stationary Alfvén wave
solutions. This exclusion region depends on the value of the local Alfvén speed VA,
plasma beta perpendicular to the magnetic field β⊥ and electron temperature
anisotropy. |
