S-bursts in Jupiter's decametric radio spectra
TLDR
In this article, the dynamic spectra of S-bursts were observed with sweep-frequency and multi-channel receivers operating at frequency ranges 21-30 and 20.20 MHz, respectively.Abstract:
Dynamic spectra of Jupiter's S-bursts are observed with sweep-frequency and multi-channel receivers operating at frequency ranges 21–30 and 20.85–23.20 MHz, respectively. Spectra obtained with time resolutions of 0.2, 0.02, and 0.004 s are compared, the frequency resolution being 50 kHz. The most normal appearance of S-bursts is in trains with a frequency range of the order of 1 MHz. Narrow-band Strains also occur. Narrow-band L-emissions in region B are often associated with S-bursts, obviously in the manner described by Flagget al. (1976). Synoptic spectral observations indicate that region B for S-bursts exhibits a drift in longitude similar to that for L-bursts. The Io phase profile for S-bursts has a maximum in the vicinity of 80° in region B and 230° in region C. S-bursts observed in 1976 have higher drift rates than those compiled by Krauscheet al. (1976). Region C bursts have simpler spectra and lower drift rates than region B bursts.read more

A scenario for Jovian S-bursts
TL;DR: In this article, an automated analysis of an extensive set of digital radio observations at very high temporal and spectral resolutions is presented, which strongly suggests that S-bursts are the cyclotron-maser emission of electron populations with ∼5 keV energy, accelerated near Io and then in quasi-adiabatic motion along magnetic field lines connecting the Io torus to Jupiter's auroral regions.

S bursts and the Jupiter ionospheric Alfvén resonator
Robert E. Ergun,Y.-J. Su,Laila Andersson,Fran Bagenal,P. A. Delemere,Robert L. Lysak,Robert J. Strangeway +6 more
TL;DR: In this article, the authors explored a possible relationship between S bursts and trapped Alfven waves in Jupiter's upper ionosphere and found that the two phenomena are colocated, suggesting such an association is possible.

Modeling Jupiter's decametric modulation lanes
TL;DR: In this paper, a grid-like interference screen composed of field-aligned columns of enhanced or depleted plasma density is located near Io's orbit close to the longitude of the sub-Earth point.

The Magnetosphere of Jupiter

TL;DR: The only solar system objects known to possess magnetic fields are the Earth, the Sun, and Jupiter as discussed by the authors, and the only evidence that Jupiter has a magnetic field is provided by its polarized radio emissions.

Radiophysics of Jupiter
TL;DR: In this article, the rotational period of the Earth's magnetic field has been studied in terms of the displacement of the displaced dipole, which is the only known explanation for the observed asymmetries in DAM and DIM.

Dynamic spectra of Jupiter's decametric emission, 1961
TL;DR: In this paper, the authors proposed a decametric emission from Jupiter and evidence for their existence is presented, based on the presence of energetic radiation belts similar to the earth's.

Redefinition of system III longitude
A. C. Riddle,James W. Warwick +1 more
TL;DR: In this paper, a new definition of the Jovian System III longitude measure has been proposed, which has been widely circulated among users and has met with general acceptance, but some errors in current calculations of System III [1957.0] are not noted so that these errors can be avoided in future calculations.
