  journal={Space Science Reviews},
This article proposes a short review of our present knowledge of solar system magnetospheres, with the purpose of placing the study of Saturn’s magnetosphere in the context of a comparative approach. We describe the diversity of solar system magnetospheres and the underlying causes of this diversity: nature and magnetization state of the planetary obstacle, presence or not of a dense atmosphere, rotation state of the planet, existence of a system of satellites, rings and neutral gas populations… Expand
Identification of Saturn's magnetospheric regions and associated plasma processes: Synopsis of Cassini observations during orbit insertion
[1] Saturn's magnetosphere is currently studied from the microphysical to the global scale by the Cassini-Huygens mission. During the first half of 2004, in the approach phase, remote sensingExpand
Energetic particles in Saturn's magnetosphere during the Cassini nominal mission (July 2004–July 2008)
Abstract In July 2004 the Cassini spacecraft began its orbital tour in the Saturnian system and performed 74 orbits during the nominal mission (July 2004–July 2008) providing data from nearly allExpand
Saturn's Auroral Response to the Solar Wind: Centrifugal Instability Model
We describe a model initially presented by Sittler et al. [2006] which attempts to explain the global response of Saturn's magnetosphere and its corresponding auroral behavior to variations in theExpand
Magnetic fields in the nearby Universe, as observed in solar and planetary realms, stars, and interstellar starforming nurseries
Abstract Here I present a survey of planetary, stellar and clumpy interstellar magnetic fields, with an emphasis on discoveries made in the last decade. Ground-based and Earth–satellite observationsExpand
Global MHD modeling of Mercury's magnetosphere with applications to the MESSENGER mission and dynamo theory
We use a global magnetohydrodynamic (MHD) model to simulate Mercury's space environment for several solar wind and interplanetary magnetic field (IMF) conditions in anticipation of the magnetic fieldExpand
Current Systems in Planetary Magnetospheres and Ionospheres
The interaction of planets with the solar wind produces a diversity of current systems, yet these can be classified into only a few different types, which include ionospheric currents, currentsExpand
Dust-plasma interaction through magnetosphere-ionosphere coupling in Saturn's plasma disk
Abstract The ion bulk speeds in the equatorial region of Saturn’s inner magnetosphere, according to data from the Langmuir Probe (LP) on board the Cassini spacecraft, are about 60% of the idealExpand
Giant magnetospheres in our solar system: Jupiter and Saturn compared
We review the current knowledge about the two biggest magnetospheres in our solar system based on the significant progress made with data from the Cassini spacecraft in orbit around Saturn sinceExpand
Ionization processes in the atmosphere of Titan II. Electron precipitation along magnetic field lines
Context. The Cassini probe regularly passes the vicinity of Titan, providing new insights into particle precipitation by use of its electron and ion spectrometers. A discrepancy between precipitationExpand
Magnetic Polarity Transitions and Biospheric Effects
This review addresses possible biospheric effects of geomagnetic polarity transitions. During a transition the magnetic field at the surface of the Earth decreases to about 10% of its current value.Expand


24 - The configuration of Jupiter's magnetosphere
A magnetosphere is a “sphere” of influence around a planet in which the forces associated with the magnetic field of the planet prevail over all other forces. The magnetic field of the planet divertsExpand
Mercury's Magnetosphere
The Mariner 10 observations of Mercury's miniature magnetosphere collected during its close encounters in 1974 and 1975 are reviewed. Subsequent data analysis, re-interpretation and theoreticalExpand
The dynamics of planetary magnetospheres
Abstract Mercury, Earth, Jupiter, Saturn, Uranus, Neptune, and the moon, Ganymede, have presently-active internal dynamos while Venus, Mars, at least two of the Galilean moons, the Earth's moon,Expand
The Magnetosphere of Jupiter
The only solar system objects known to possess magnetic fields are the Earth, the Sun, and Jupiter. The field of the Earth can be measured directly, while that of the Sun has been deduced from theExpand
Dynamics of the Jovian magnetosphere
[1] Most regions of the Jovian magnetosphere covered by the Galileo spacecraft measurements undergo quasi-periodic modulations with a time period of several Earth days. These modulations appear inExpand
Magnetospheric and Plasma Science with Cassini-Huygens
Magnetospheric and plasma science studies at Saturn offer a unique opportunity to explore in-depth two types of magnetospheres. These are an ‘induced’ magnetosphere generated by the interaction ofExpand
The Current Systems of the Jovian Magnetosphere and Ionosphere and Predictions for Saturn
Magnetized plasmas in motion inevitably generate currents and the magnetized plasmas that form the magnetospheres of the outer planets are no exception. Although a focus on the current systems tendsExpand
Giant Planet Ionospheres and Thermospheres: The Importance of Ion-Neutral Coupling
Planetary upper atmospheres-coexisting thermospheres and ionospheres-form an important boundary between the planet itself and interplanetary space. The solar wind and radiation from the Sun may reactExpand
Detection of the hydroxyl radical in the Saturn magnetosphere
THE magnetosphere in the vicinity of the orbits of Saturn's icy satellites consists of a low-density plasma, in which the electrons are an order of magnitude cooler than the accompanying heavy ions1.Expand
The magnetic field and magnetospheric configuration of Uranus
A significant and unique planetary magnetic field discovered by Voyager 2 is presented. A large tilt of 58.6 deg of the magnetic-dipole axis from the rotation axis was found. Combined with a largeExpand
