| Zusammenfassung |
| MHD solitons are studied in a model where the usual Hall-MHD
model is extended to include the finite Larmor radius (FLR) corrections to the
pressure tensor. The resulting 4-dimensional set of differential equations is treated
numerically. In this extended model, the point at infinity can be of several types.
Necessary for the existence of localized solutions is that it is either a saddle-saddle,
a saddle-center, or, possibly, a focus-focus. In cases of saddle-center, numerical
solutions for localized travelling structures have been obtained, and compared with
corresponding results from the Hall-MHD model. |
