The best constraints on the internal structures of giant planets have historically come from measurements of their gravity fields[1, 2, 31]. These gravity data are inherently mostly sensitive to a planet’s outer regions, providing only loose constraints on the deep interiors of Jupiter[2, 4, 2] and Saturn[6, 7]. This fundamental limitation stymies efforts to measure the mass and compactness of these planets’ cores, crucial properties for understanding their formation pathways and evolution[8, 9… 
Constraining Saturn’s Interior with Ring Seismology: Effects of Differential Rotation and Stable Stratification
Normal mode oscillations in Saturn excite density and bending waves in the C ring, providing a valuable window into the planet’s interior. Saturn’s fundamental modes (f-modes) excite the majority of
Kronoseismology. VI. Reading the Recent History of Saturn’s Gravity Field in Its Rings
Saturn’s C ring contains multiple structures that appear to be density waves driven by time-variable anomalies in the planet’s gravitational field. Semiempirical extensions of density wave theory
The Dynamical Viability of an Extended Jupiter Ring System
Planetary rings are often speculated as being a relatively common attribute of giant planets, partly based on their prevalence within the solar system. However, their formation and sustainability
The Origin and Evolution of Saturn: A Post-Cassini Perspective
The Saturn system has been investigated extensively since the early 1970s, with the bulk of these data generated by the Cassini-Huygens Mission between 2004 and 2017. A major thrust of those
The Gravitational Imprint of an Interior–Orbital Resonance in Jupiter–Io
At mid-mission perijove 17, NASA’s Juno mission has revealed a 7σ discrepancy between Jupiter’s observed high-degree tidal response and the theoretical equilibrium tidal response, namely, the Love
Theory of Figures to the Seventh Order and the Interiors of Jupiter and Saturn
Interior modeling of Jupiter and Saturn has advanced to a state where thousands of models are generated that cover the uncertainty space of many parameters. This approach demands a fast method of

The Promise and Limitations of Precision Gravity: Application to the Interior Structure of Uranus and Neptune
We study the constraining power of a high-precision measurement of the gravity field for Uranus and Neptune, as could be delivered by a low-periapse orbiter. Our study is practical, assessing the
Partially Diffusive Helium-Silica Compound in the Deep Interiors of Giant Planets
Helium is the second most abundant element in the universe, and together with silica, they are major components of giant planets. Exploring the reactivity and state of helium and silica under high


Cassini Ring Seismology as a Probe of Saturn’s Interior. I. Rigid Rotation
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 constrained by
Memoirs of a Giant Planet
Saturn is ringing weakly. Exquisite data from the Cassini mission reveal the presence of f-mode oscillations as they excite density waves in Saturn’s rings. These oscillations have displacement
Saturn's Deep Atmospheric Flows Revealed by the Cassini Grand Finale Gravity Measurements
How deep do Saturn's zonal winds penetrate below the cloud level has been a decades‐long question, with important implications not only for the atmospheric dynamics but also for the interior density
Combined magnetic and gravity measurements probe the deep zonal flows of the gas giants
<p>The strong zonal flows observed at the cloud-level of the gas giants extend thousands of kilometers deep into the planetary interior, as indicated by the Juno and Cassini gravity measurements.
Planetary Acoustic Mode Seismology: Saturn's Rings
We examine the hypothesis that the rings of Saturn may act as a seismograph, recording gravitational perturbations associated with acoustic oscillation modes of the planet. The resonant interaction
Measurement and implications of Saturn’s gravity field and ring mass
The results show that Saturn's rings are substantially younger than the planet itself and constrain models of their origin, and five small moons located in and around the rings are presented, confirming that the flows are very deep and likely extend down to the levels where magneticipation occurs.
The fuzziness of giant planets' cores
Giant planets are thought to have cores in their deep interiors, and the division into a heavy-element core and hydrogen–helium envelope is applied in both formation and structure models. We show
Saturn's Rings as a Seismograph to Probe Saturn's Internal Structure
As it has already done for Earth, the Sun, and the stars, seismology has the potential to radically change the way the interiors of giant planets are studied. In a sequence of events foreseen by only
