| Zusammenfassung |
| We investigate the
nature of nonlinear waves propagating transverse to the magnetic field in
a bi-ion plasma including plasma pressure. By using the conservation laws
derived from the multi-ion fluid equations the system may be described by
a single order differential equation whose properties control the
structure of the flow and the magnetic field. Compressive solitons exist
in specific ranges of the characteristic Mach numbers. Various features of
solitons differ in different existence "windows". For example,
there are solitons that contain a strong proton rarefaction core embedded
in the main compressional structure. Compressive solitons are found in a
wide range of flow parameters. Finite ion pressure introduces critical
Mach numbers. In contrast to a plasma consisting only of protons and
electrons these singular points are reached where a specific combination
of ion and electron speeds lies on particular locii, in multi-parameter
space, which corresponds to the generalized "sonic point" of the
compound system. |
