Earth's magnetic field is generated by fluid motions in the outer core. This geodynamo has
operated for over 3.4 billion years. However, the mechanism that has sustained the …

Abstract The Galileo mission to Jupiter revealed that Europa is an ocean world. The Galileo
magnetometer experiment in particular provided strong evidence for a salty subsurface …

Precession of planets or moons affects internal liquid layers by driving flows, instabilities and
possibly dynamos. The energy dissipated by these phenomena can influence orbital …

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 …

A growing number of satellites in the outer solar system likely have global oceans beneath
their outer icy shells. While the presence of liquid water makes these ocean worlds …

Pressures in the hydrospheres of large ocean worlds extend to ranges exceeding those in
Earth deepest oceans. In this regime, dense water ices and other high-pressure phases …

Of profound astrobiological interest, Enceladus appears to have a global saline subsurface
ocean, indicating water-rock reaction at present or in the past, an important mechanism in …

Ocean worlds are prevalent in the solar system. Focusing on Enceladus, Titan, Europa, and
Ganymede, I use rotating convection theory and numerical simulations to predict ocean …

We present a new model of Enceladus' internal structure based on the recent shape model
by Tajeddine et al.(2017) and the gravity model by Iess et al.(2014). Assuming that the rocky …

Previous studies that have considered the ocean circulation on Enceladus have generally
assumed the salinity to be Earth-like. However, according to observations and geochemical …
