| Zusammenfassung |
| The value of effective polytropic indices in turbulent anisotropic magnetised plasmas is
numerically calculated within double-adiabatic magnetohydrodynamic theory. There it is
suggested that in the plasma different magnetosonic waves and temperature-anisotropy driven
waves are excited. In comparison to former works, the plasma anisotropy is taken into
account also - or more exactly - in the wave dispersion relations. As result, the dependence of
the polytropic indices on plasma density, temperature, magnetic field intensity, and
propagation direction of the excited waves is obtained. Applications are presented for the
transition regions between the solar wind and the magnetospheres of the Earth and Jupiter. |
