Cassini magnetometer observations during Saturn orbit insertion.
Cassini's successful orbit insertion has provided the first examination of Saturn's magnetosphere in 23 years, revealing a dynamic plasma and magnetic environment on short and long time scales. There has been no noticeable change in the internal magnetic field, either in its strength or its near-alignment with the rotation axis. However, the external magnetic field is different compared with pa...
متن کاملStellar Occultation Saturn ' s Upper Observations of Atmosphere
We have analyzed three stellar occultation observations of Saturn's upper atmosphere during the years 1989 to 1995. These occultations probed the stratosphere at pressure levels about 0.5 to 20 pbars, intermediate to those probed by the Pioneer 11, Voyager I and II radio and ultraviolet occultations. The time span of the earlier occultations and the observation of a higher latitude occultation ...
متن کاملPlanetary radio astronomy observations from voyager 2 near saturn.
Planetary radio astronomy measurements obtained by Voyager 2 near Saturn have added further evidence that Saturnian kilometric radiation is emitted by a strong dayside source at auroral latitudes in the northern hemisphere and by a weaker source at complementary latitudes in the southern hemisphere. These emissions are variable because of Saturn's rotation and, on longer time scales, probably b...
متن کاملNew Jupiter and Saturn formation models meet observations
The wealth of observational data about Jupiter and Saturn provides strong constraints to guide our understanding of the formation of giant planets. The size of the core and the total amount of heavy elements in the envelope have been derived from internal structure studies by Saumon & Guillot (2004). The atmospheric abundance of some volatile elements has been measured in situ by the Galileo pr...
متن کاملHorsing around on Saturn.
On the basis of simple statistical mechanical models, the prevailing view of the rings of Saturn is that they are unstable and must therefore have been formed rather recently. In this paper, we argue that the Saturn rings and inner moons are in much more stable orbits than previously thought and, therefore, that they likely formed together as part of the initial formation of the solar system. T...
