N-body Simulations of Satellite Formation around Giant Planets: Origin of Orbital Configuration of the Galilean Moons

, 2012
As the number of discovered extrasolar planets has been increasing, diversity of planetary systems requires studies of new formation scenarios. It is important to study satellite formation in circumplanetary disks, which is often viewed as analogous to ...

Probing the origin of the dark material on Iapetus [PDF]

, 2009
Among the icy satellites of Saturn, Iapetus shows a striking dichotomy between its leading and trailing hemispheres, the former being significantly darker than the latter.

Enough Sulfur and Iron for Potential Life Make Enceladus’s Ocean Fully Habitable

The Astrophysical Journal Letters
The Cassini spacecraft revealed life-forming elements like CHNOP and diverse organic compounds from Enceladus’s ocean. However, the availability of minor but bio-essential nutrients such as iron and sulfur remains unknown.

TRAPPED‐S, a New Environment Model Framework for Saturn: Focus on Radiation‐Specification Model

Journal of Geophysical Research: Space Physics, Volume 130, Issue 11, November 2025.
Abstract As space agencies contemplate missions to the outer planets' systems and moons, entailing prolonged observations via local orbiters or potential landers, meticulous assessment of the local environment—encompassing radiation and plasma conditions—is paramount for the design of both the platform and scientific payload.

Librational response of a deformed 3-layer Titan perturbed by non-keplerian orbit and atmospheric couplings

, 2014
The analyses of Titan's gravity field obtained by Cassini space mission suggest the presence of an internal ocean beneath its icy surface. The characterization of the geophysical parameters of the icy shell and the ocean is important to constrain the ...

Retrograde Predominance of Small Saturnian Moons Reiterates a Recent Retrograde Collisional Disruption

The Planetary Science Journal
We report the discovery and careful orbital determination of 64 new irregular moons of Saturn found in images taken using the Canada–France–Hawaii Telescope from 2019 to 2021, bringing the total number of Saturnian irregulars to 122.

Ocean Worlds Maintained by Ocean Tidal Heat Expected on Several Uranian Moons

Geophysical Research Letters, Volume 52, Issue 20, 28 October 2025.
Abstract In recent NASA decadal surveys, detecting oceans among Uranus' moons has been identified as a research priority in future missions. Currently, the prevailing view in planetary science is that the likelihood of finding oceans is highest on the larger moons, Titania and Oberon, due to their higher integrals of radiogenic heat sources. This study

Extensional tectonics of the Saturnian Satellites [PDF]

, 1985
The saturnian satellites were imaged by the Voyager spacecraft at sufficient resolutions to reveal landforms that indicate histories of extensional tectonics for several of these bodies.

A JWST Study of CO2 on the Satellites of Saturn

The Planetary Science Journal
Solid state CO _2 has been detected throughout the outer solar system, even at temperatures where crystalline CO _2 is unstable, requiring that the CO _2 be trapped in a separate host material. The Saturnian satellites provide an ideal laboratory for the

A Specification Model of Saturn's Plasma Environment

Journal of Geophysical Research: Space Physics, Volume 130, Issue 10, October 2025.
Abstract We present the first empirical‐based specification model of Saturn's plasma environment based on the analysis of all publicly available plasma moment data sets derived using multiple techniques from Cassini observations made by the Cassini Plasma Spectrometer and the Radio and Plasma Wave Science instrument.
