Zusammenfassung |
Alfvénic solutions of nondissipative MHD are
entirely determined by their magnetic configuration. With the supplementary
assumption of incompressibility any solenoidal field can be used to construct
an Alfvénic solution. It is demonstrated that for nondissipative and
compressible MHD the energy equation constrains the magnetic field of Alfvénic
solutions to have a constant strength along field lines. Some topological
solitons known in nondissipative and incompressible MHD do not have this
property. New localized axisymmetric Alfvénic solutions of nondissipative and
compressible MHD are explicitly constructed. |
