Cassini Ring Seismology as a Probe of Saturn's Interior I: Rigid Rotation

, 2018
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 the gravity field and compute their adiabatic mode ...

Cold and Hot Electron Populations Observed by Juno‐JADE in the Jovian Magnetodisc

Geophysical Research Letters, Volume 52, Issue 17, 16 September 2025.
Abstract Despite their importance to a variety of plasma processes in Jupiter's magnetosphere, properties of the thermal and suprathermal electrons have been sparsely reported in past literature. To address this gap, we used data from Juno's Jovian Auroral Distributions Experiment Electron sensors to survey electron properties in Jupiter's magnetodisc ...

Water Transport from Enceladus to the Rings

The Planetary Science Journal
Enceladus continuously ejects approximately 300 kg s ^−1 of water vapor from its south polar regions, forming an extensive neutral gas torus around Saturn.

The Capture of Centaurs as Trojans

, 2005
Large scale simulations of Centaurs have yielded vast amounts of data, the analysis of which allows interesting but uncommon scenarios to be studied. One such rare phenomenon is the temporary capture of Centaurs as Trojans of the giant planets.

A Comprehensive Framework for Assessing Terrestrial Analogue Field Sites for Ocean Worlds

Journal of Geophysical Research: Planets, Volume 130, Issue 9, September 2025.
Abstract Field studies at terrestrial analogue sites represent an important contribution to the science of ocean worlds. The value of the science and technology investigations conducted at field analogue sites depends on the relevance of the analogue environment to the target ocean world.

Origin of Hyperion and Saturn’s Rings in a Two-stage Saturnian System Instability

The Planetary Science Journal
The age of the rings and some of the moons of Saturn is an open question, and multiple lines of evidence point to a recent (few hundred Myr ago) cataclysm involving the disruption of past moons. The main driver of the evolution of the Saturnian system is

The Role of Ejecta in the Small Crater Populations on the Mid-Sized Saturnian Satellites

, 2011
We find evidence that crater ejecta play an important role in the small crater populations on the Saturnian satellites, and more broadly, on cratered surfaces throughout the Solar System. We measure crater populations in Cassini images of Enceladus, Rhea,

The Bombardment History of the Giant Planet Satellites

The Planetary Science Journal
The origins of the giant planet satellites are debated, with scenarios including formation from a protoplanetary disk, sequential assembly from massive rings, and recent accretion after major satellite–satellite collisions.

On the origin of the Trojan asteroids: Effects of Jupiter's mass accretion and radial migration [PDF]

, 2000
We present analytic and numerical results which illustrate the effects of Jupiter's accretion of nebular gas and the planet's radial migration on its Trojan companions.

Raman Spectroscopy of Salt Deposits from the Simulated Subsurface Ocean of Enceladus

The Planetary Science Journal
Enceladus may host a subsurface ocean with biologically relevant chemistry. Plumes released from this ocean preserve information on its chemical state, and previous analyses suggest weakly to strongly alkaline pH.
