Scientific paper

A model of Jupiter's nightside magnetosphere, based on the theory of self-consistent axisymmetric MHD equilibrium, is presented. The model assumes that the plasma forms a thin disk, while the magnetopause is considered as a surface that confines the magnetic flux of the dipole and of the current disk. Data from the Voyager missions were used as input for the solution of the equation determining the self-consistent equilibrium magnetic structure, and computations are performed by varying the hot-plasma composition and the current disk cutoff radius. It was found that, with sufficiently large disks, the magnetic configuration has an X line and an O line, with the X line located between 37 and 45 Jovian radii; the position of O line is less certain. The results of the model agree well with the magnetic field data in the tail.
