The theory of spiral density waves had its origin approximately six decades ago in an
attempt to reconcile the winding dilemma of material spiral arms in flattened disk galaxies …

The best constraints on the internal structures of giant planets have historically originated
from measurements of their gravity fields,–. These data are inherently mostly sensitive to a …

The Cassini-Huygens mission to Saturn provided a close-up study of the gas giant planet, as
well as its rings, moons, and magnetosphere. The Cassini spacecraft arrived at Saturn in …

The Juno spacecraft reached the mid‐point of its nominal mission in December 2018, after
completing 17 perijove passes. Ten of these were dedicated to the determination of the …

We put together a first-principles equation of state (FPEOS) database for matter at extreme
conditions by combining results from path integral Monte Carlo and density functional …

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 …

Seismology of the gas giants holds the potential to resolve long-standing questions about
their internal structure and rotation state. We construct a family of Saturn interior models …

The Juno spacecraft has been collecting data to shed light on the planet's origin and
characterize its interior structure. The onboard gravity science experiment based on X-band …

The ice giant planets, Uranus and Neptune, represent an important and relatively
unexplored class of planet. Most of our detailed information about them comes from fleeting …

Seismology allows for direct observational constraints on the interior structures of stars and
planets. Recent observations of Saturn's ring system have revealed the presence of density …
