Astrophysical fluid bodies that orbit close to one another induce tidal distortions and flows
that are subject to dissipative processes. The spin and orbital motions undergo a coupled …

Many outer solar system bodies are thought to harbor liquid water oceans beneath their ice
shells. This article first reviews how such oceans are detected. We then discuss how they …

Several planetary satellites apparently have subsurface seas that are of great interest for,
among other reasons, their possible habitability. The geologically diverse saturnian satellite …

Saturn is orbited by dozens of moons, and the intricate dynamics of this complex system
provide clues about its formation and evolution. Tidal friction within Saturn causes its moons …

Moons potentially harbouring a global ocean are tending to become relatively common
objects in the Solar System. The presence of these long-lived global oceans is generally …

The inner moons of Jupiter and Saturn migrate outwards due to tidal energy dissipation
within the planets, the details of which remain poorly understood. We demonstrate that …

The intense plume activity at the South Pole of Enceladus together with the recent detection
of libration hints at an internal water ocean underneath the outer ice shell. However, the …

Abstract The JUpiter ICy moons Explorer (JUICE) of ESA was launched on 14 April 2023
and will arrive at Jupiter and its moons in July 2031. In this review article, we describe how …

Its extraordinary level of geologic activity, its potential for habitability, and the prospects of
returning samples from its plume of erupting water ice make Saturn's small (∼ 500 km …

Using astrometric observations spanning more than a century and including a large set of
Cassini data, we determine Saturn's tidal parameters through their current effects on the …
