We review our understanding of Saturn's rings after nearly 6 years of observations by the
Cassini spacecraft. Saturn's rings are composed mostly of water ice but also contain an …

Uranus and Neptune are the least-explored planets in our Solar System. This paper
summarizes mysteries about these incredibly intriguing planets and their environments …

The origin of Saturn's massive ring system is still unknown. Two popular scenarios—the tidal
splitting of passing comets and the collisional destruction of a satellite—rely on a high …

The origin of rings around giant planets remains elusive. Saturn's rings are massive and
made of 90–95% of water ice with a mass of∼ 10 19 kg. In contrast, the much less massive …

We assess the prospect of using ring seismology to probe the interiors of the ice giants
Uranus and Neptune. We do this by calculating normal-mode spectra for different interior …

The origin and long-term evolution of Saturn's rings is still an unsolved problem in modern
planetary science. In this chapter we review the current state of our knowledge on this long …

Using Cassini images, we examine the faint material along the orbits of Methone, Anthe and
Pallene, three small moons that reside between the orbits of Mimas and Enceladus. A …

The appearance of debris disks around distant stars depends upon the scattering/phase
function (SPF) of the material in the disk. However, characterizing the SPFs of these …

Saturn's magnetosphere has been studied extensively by the Cassini spacecraft during the
last 6 years. We present mission‐averaged energetic proton and electron measurements …

We present Cassini data revealing that protons between a few keV and about 100 keV
energy are not stably trapped in Saturn's inner magnetosphere. Instead these ions are …
