Numerical Simulation of Rotation-Driven Plasma Transport In the Jovian Magnetosphere. By Richard A. Wolf. Abstract. A Jupiter version of the Rice Convection Model (RCM-J) was developed with support of an earlier NASA SR&T grant.

The numerical simulations of a heavy flux tube motion in the equilibrium models of Jupiter's inner magnetosphere for this period yield two results: (1) the heavy flux tube is unstable in a model with only cold plasma included and (2) the heavy flux tube is stable in models with both cold and hot plasma by: In this chapter we present a review of plasma transport in the magnetospheres of the rapidly rotating outer planets Jupiter and Saturn with emphasis on the effects of magnetic reconnection.

Unlike the Earth’s magnetosphere where reconnection is the dominant transport mechanism, atmospherically driven corotation dominates at Jupiter and by: 2.

A centrifugally confined plasma utilizes centrifugal forces from supersonic plasma rotation to augment the conventional magnetic confinement of fusion plasmas. Appropriately used, plasma pressure can be contained along the magnetic field lines, allowing for “open” configurations, introducing flexibility in design.

The axisymmetric equilibrium of one such system, a single coil configuration, is investigated by: 4. Galileo evidence for rapid interchange transport in the Io torus Numerical simula-tion of plasma transport driven by the Io torus Numerical simulation of torus-driven transport in the Jovian.

1 Introduction. A rotation‐driven planetary magnetosphere is powered, at least in part, by rotational energy extracted from the planet by active plasma sources operating within the magnetosphere [e.g., Dessler, ; Eviatar and Siscoe, ].The most thoroughly observed examples are the magnetospheres of Jupiter and Saturn, thanks largely to the orbital missions Cited by: 2.

Numerical experiments are performed to study the possibility of long-lived vortex generation in rotating convection zones. The domain of computation is a rectangular box with fixed latitude.

The fully compressible fluid equations are solved using an explicit, strongly conservative finite difference by: The most striking feature of the Jovian plasma-wave observations is the very close similarity to the plasma-wave phenomena observed in the earth's magnetosphere.

In a description of the plasma-wave results obtained with the aid of Voyager, the observed phenomena are discussed in several broad categories. Ioaniddis, N. Brice, Plasma densities in the Jovian magnetosphere: plasma slingshot or Maxwell demon.

S.J. Bolton et al. Fig. 1 (A) The magnetosphere of Jupiter extends 63–92 Jovian radii in the direction towards the Sun, with a tail that stretches beyond the orbit of Saturn >4 AU, and occupies a volume over a thousand times that of the Sun. (B) Intense auroral emissions are signatures of the coupling between the planet and the magnetospheric.

An example map, Fig. 1 shows the normalized optical free–free emissivity in logarithmic scale. This map was created from simulation data taken at the snapshot time of wire-crossing times. At this time, the wind coming into the grid from the left side had deflected around the wire, and in the course of its navigation around the obstacle components of the magnetosphere Cited by: 3.

A series of plasma voids ("dropouts") was observed by the Plasma Science (PLS) experiment in Jupiter's magnetosphere during the Voyager 2 encounter with that planet. A reexamination of Voyager 2 data has led us to conclude that the dropout phenomenon cannot be a manifestation of a plasma wake produced by Ganymede.

plasma sources in the close-in equatorial magnetosphere parallels conditions at Jupiter. This suggests that we need to study both Jupiter and Earth when thinking about what to anticipate from Cassinis exploration of Saturns magnetosphere.

This paper addresses issues relevant to plasma transport and acceleration in all three magnetospheres. Transport and entry of plasma clouds/jets across transverse magnetic discontinuities: Simulation setup The numerical simulations are performed in a three-dimensional geometry that allows the simultaneous investigation of the plasma.

The dynamic plasma flow of the Jovian magnetosphere shapes and distorts the draped field around the icy moons. In a km Ganymede orbit, the expected induction signal is 10’s of nT. The field perturbations from the plasma interactions are expected to be of the same order or more.

In the present work, the Direct Simulation Monte Carlo (DSMC) method is used to simulate the interaction of Io's atmosphere with the Jovian plasma torus and the results are compared to observations. These comparisons help constrain the relative contributions of atmospheric support as well as highlight the most important physics in Io's atmosphere.
