| description | The Jovian paraboloid magnetospheric model is
applied for the investigation of the planet's auroral emission and plasma disk
structure in the middle magnetosphere. Jupiter's auroral emission
demonstrates the electrodynamic coupling between the ionosphere and
magnetosphere. For comparison of different regions in the ionospheric level and
in the magnetosphere, the paraboloid model of the global magnetospheric
magnetic field is used. This model provides mapping along highly-conducting
magnetic field lines. The paraboloid magnetic field model is also applied for
consideration of the stability of the background plasma disk in the rotating
Jupiter magnetosphere with respect to the flute perturbations. Model
radial distribution of the magnetic field and experimental data on the plasma
angular velocity in the middle Jovian magnetosphere are used. A dispersion
relation of the plasma perturbations in the case of a perfectly conducting
ionosphere is obtained. Analyzing starting conditions of a flute
instability in the disk, the "threshold" radial profile of the plasma density
is determined. An application of the results obtained to the known data on the
Jovian plasma disk is discussed. |
