A STATIC STRUCTURAL MODEL OF THE OUTER MAGNETOSPHERE OF JUPITER

In this paper the ideal-state MHDequations are solved: the results show that there are two kinds of relationship between the variables and Z (the distame from equator) in the plasma sheet.One is a hyperbolic function,while the other is a trigonometric function.Observations would seem to agree with the hyperbolic function.Simple distribution formulas of pressure,density,temperature,magnetic field and current density in the plasma sheet are deduced.The relationship between the variables and radial distance r are: P_o(r)～r^-3.4,j_o(r)～r^-1.7. For an adiabatie proceess,p_o(r)～r^-2.04,T_o(r)～r^-1.36.For an isothermal process,p_o(r)～r^-3.4,T=constant.Finally,the influences of the magnetic anomaly on the outer magnetosphere are dicussed.
