The morphology of Saturn's ultraviolet aurora
[1] Spectrographic images in the far ultraviolet, obtained from observations made from 2007 to 2009, are used to quantify and compare the morphology of Saturn's northern and southern aurora in localExpand
Discovery of a north-south asymmetry in Saturn's radio rotation period
[1] For many years it has been known that Saturn emits intense radio emissions at kilometer wavelengths and that this radiation is modulated by the rotation of the planet at a rate that varies by upExpand
General characteristics of hot plasma and energetic particles in the Saturnian magnetosphere: Results from the Voyager spacecraft
The low energy charged particle (LECP) experiment on the Voyager 1 and 2 spacecraft made measurements of the intensity, energy spectra, and spatial distributions of ions (30 keV ≲ E ≲ 150 MeV) andExpand
The Dynamics of Saturn's Magnetosphere
The dynamics of Saturn's magnetosphere differs considerably from that at the Earth. Saturn's magnetosphere responds to both external and internal drivers. The solar wind ram pressure, rather than theExpand
Recurrent energization of plasma in the midnight-to-dawn quadrant of Saturn's magnetosphere, and its relationship to auroral UV and radio emissions
Abstract We demonstrate that under some magnetospheric conditions protons and oxygen ions are accelerated once per Saturn magnetosphere rotation, at a preferred local time between midnight and dawn.Expand
Electron periodicities in Saturn's outer magnetosphere
[1] The Magnetospheric Imaging Instrument/Low-Energy Magnetospheric Measurements Sensor (MIMI/LEMMS) instrument on the Cassini spacecraft has measured energetic electrons in the energy range 20–300Expand
Periodicities in Saturn's magnetosphere
[1] Although the exact rotation period of Saturn is unknown, Saturn's magnetosphere displays an abundance of periodicities near ~10.7 h. Such modulations appear in charged particles, magnetic fields,Expand
Charged particle periodicities in Saturn's outer magnetosphere
[1] A Lomb periodogram analysis is applied to charged particle data from the LEMMS/CHEMS instruments on the Cassini spacecraft. The data represent count rates, averaged within 30 min bins, fromExpand
Spin‐period effects in magnetospheres with no axial tilt
[1] A magnetic axis that is tilted with respect to the spin axis causes waves that generate spin-periodic effects in a planet's outer magnetosphere. Saturn's magnetic axis is aligned with its spinExpand
Evidence for spiral pattern in Saturn's magnetosphere using the new SKR longitudes
[1] The periodicities in electrons observed in Saturn's magnetosphere are examined using the new longitude system based on a drifting signal of Saturn kilometric radiation (SKR). When averaged intoExpand
