Unveiling What Makes Saturn Ring: Quantifying the Amplitudes of Saturn's Planetary Normal‐Mode Oscillations and Trends in C‐Ring Properties Using Kronoseismology (VII)

Journal of Geophysical Research: Planets, Volume 130, Issue 4, April 2025.
Abstract Certain spiral density waves in Saturn's rings are generated through resonances with planetary normal modes, making them valuable probes of Saturn's internal structure. Previous research has primarily focused on the rotation rates of these waves. However, other characteristics of these waves also contain valuable information about the planet's

A Centroiding Algorithm for Point-source Trails

The Astronomical Journal
Astrometric measurements are significantly challenged by the relative motion between the point source and the telescope, primarily due to the difficulty in accurately determining the position of the point source at the mid-exposure moment.

Gravity and Radio Science Investigation at the Moons of Uranus to Reveal Subsurface Oceans and Characterize Interior Structures

Journal of Geophysical Research: Planets, Volume 130, Issue 4, April 2025.
Abstract The prospect that the five major moons of Uranus could host subsurface oceans makes them high‐priority targets for future exploration. Different techniques can be used to search for deep oceans in these objects. Here, we focus on ocean detection and characterization from measurements of the moons' response to the gravitational tides and ...

Saturn's icy satellites and rings investigated by Cassini - VIMS. III. Radial compositional variability

, 2012
In the last few years Cassini-VIMS, the Visible and Infared Mapping Spectrometer, returned to us a comprehensive view of the Saturn's icy satellites and rings. After having analyzed the satellites' spectral properties (Filacchione et al.

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.

The Distribution of Linear Virgae Across the Saturnian Moons

Geophysical Research Letters, Volume 52, Issue 6, 28 March 2025.
Abstract Linear virgae are long (10–100s km), narrow (<5 km), and bright features, first found on the surface of Dione. On Dione, linear virgae run parallel to the equator and are found in the low‐to‐mid latitudes. Linear virgae are likely formed by a process that involves the emplacement of materials from an exogenic Chronocentric (Saturn centric), or

Topographic Relaxation of Complex Impact Craters in a Clathrate Crust on Titan

The Planetary Science Journal
Titan’s impact craters are significantly shallower than fresh craters on Ganymede, which are often used as templates for fresh craters on Titan. The presence of a clathrate crust on Titan, which would insulate the ice shell and maintain warmer ice near ...

Saturn's Small‐Scale Winds Revealed by Its High‐Degree Gravity Field

Geophysical Research Letters, Volume 52, Issue 5, 16 March 2025.
Abstract During its Grand Finale, the Cassini spacecraft collected crucial gravity data, revealing Saturn's low‐degree gravity harmonics and large‐scale zonal winds extending about 8,000 km deep. However, determining the high‐degree gravity field, essential for understanding small‐scale atmospheric dynamics, is challenging due to the limited spatial ...

Exploring the Interior Structure and Mode of Tidal Heating in Enceladus

The Planetary Science Journal
Enceladus is among the most intriguing bodies in the solar system due to its astrobiological potential. Determining the extent and duration of habitability (i.e., sustained habitability ) requires characterizing the interior properties and the level and ...
