Abstract Five closely spaced magnetic field directional discontinuities observed by Voyager 1 late on 2 March 1979 are analyzed using a variance technique. These discontinuities showed magnetic field signatures characteristic of magnetopause crossings occurring periodically at ≈ 36 min intervals but without dramatic changes in the low energy ( 5 ...

Plasmaspheres within the Jovian magnetosphere can arise from three distinct types of processes: (1) by a photoelectron (positive ion) flux from the planetary ionosphere (the source type of earth's plasmasphere), (2) by ionization of the atmospheres and neutral particle tori of the satellites, and (3) by ionization of the neutral interstellar medium ...

The results of further measurements of the Jovian ring system are presented. The system has three major components: the bright ring, the faint sheet, and the out‐of‐plane halo. The bright ring has an outer radius of 1.81±0.01 RJ, an inner radius 1.72±0.01 RJ, an eccentricity not greater than 0.003 and a normal optical depth 3 × 10−5.

This paper reports results obtained on ionosphere formation in the Jovian upper atmosphere with special reference to some of the recently available reaction rates, and to recent models of the Jovian neutral atmosphere based on the possibility of a warmer mesopause.

Space Science Reviews, 1979
Magnetic field measurements made by the vector helium magnetometers on board Pioneers-10 and 11 reveal the existence of a current sheet (thickness ∼2R J) carrying an eastward current. Self-consistent studies of the current sheet show that the magnitude of the current is of the order of 10+2 Am+1 and that the current is carried by a hot (T>1 keV) plasma,

We present further results of our observations of the nebula of singly ionized sulfur in the magnetosphere of Jupiter. We have calculated the occupation numbers of the five lowest energy levels of ionized sulfur and have used their results together with our observed intensities to evaluate the number density of ionized sulfur.

A brief review of the history of Jovian satellite nomenclature is given to indicate the background for the names proposed for the numbered satellites. The new names are consistent with established tradition and should cause minimal confusion with other named objects in the solar system.

Auroral and polar cap emissions in a model Jovian atmosphere are determined for proton precipitation. The incident protons, which are characterized by representative spectra, are degraded in energy by applying the continuous slowing down approximation.

ABSTRACTLying in Jupiter's equatorial plane is a diaphanous ring having little substructure within its three components (main band, faint disk, and halo). Micron-sized grains account for much of the visible ring, but particles of centimeter sizes and larger must also be present to absorb charged particles.

Jovian magnetospheric processes
AIP Conference Proceedings, 1986Jupiter's rotational energy (6 x 10 to the 34th J) powers a large number of processes such as auroral UV emission, radio waves, and charged particle energization. How the rotational energy may be dissipated by injection of plasma, magnetic pumping and field aligned electric fields is described.
