Are Thalassa and Despina in Resonance Lock with Neptune's Oscillations?
Matija Äuk, Harrison F. Agrusa, Marina BrozoviÄ +1
The two innermost moons of Neptune, Naiad and Thalassa, are currently in a 73:69 mean-motion resonance. This resonance relies on the large inclination of Naiad, and we estimate tha…
Unveiling What Makes Saturn Ring: Quantifying the Amplitudes of Saturn's Planetary Normal-Mode Oscillations and Trends in C-Ring Properties Using Kronoseismology (VII)
Victor M Afigbo, Matthew M Hedman, Phillip Nicholson +4
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 re…
Setting the Stage for Uranian Seismology from Rings and Radial Velocities
Christopher R. Mankovich, A. James Friedson, Marzia Parisi +6
A Uranus orbiter would be well positioned to detect the planet's free oscillation modes, whose frequencies can resolve questions about Uranus's weakly constrained interior. We calc…
A Survey of Cassini Images of Spokes in Saturn's Rings: Unusual Spoke Types and Seasonal Trends
S. R. Callos, M. M. Hedman, D. P. Hamilton
Spokes are localized clouds of fine particles that appear over the outer part of Saturn's B ring. Over the course of the Cassini Mission, the Imaging Science Subsystem (ISS) obtain…
