Spectral trends across the rings and inner moons of Uranus and Neptune from JWST NIRCam images

M. M. Hedman, I. de Pater, R. Cartwright +8

JWST NIRCam images provide low-resolution spectra of the rings and inner moons orbiting Uranus and Neptune. These data reveal systematic variations in spectral parameters like the…

Understanding the formation of Saturn's regular moons in the context of giant planet moons formation scenarios

Michel Blanc, Aurélien Crida, Yuhito Shibaike +7

This article explores the different formation scenarios of the Kronian moons system in the context of a highly dissipative Saturn, with the objective of identifying the most likely…

Water-Ice Dominated Spectra of Saturn's Rings and Small Moons from JWST

M. M. Hedman, M. S. Tiscareno, M. R. Showalter +11

JWST measured the infrared spectra of Saturn's rings and several of its small moons (Epimetheus, Pandora, Telesto and Pallene) as part of Guaranteed Time Observation program 1247.…

Long-Term Evolution of the Saturnian System

Matija Ćuk, Maryame El Moutamid, Giacomo Lari +5

Here we present the current state of knowledge on the long-term evolution of Saturn's moon system due to tides within Saturn. First we provide some background on tidal evolution, o…

Mass Derivation of planets K2-21b and K2-21c from Transit Timing Variations

Maryame El Moutamid, Kevin B. Stevenson, Billy Quarles +5

While various indirect methods are used to detect exoplanets, one of the most effective and accurate methods is the transit method, which measures the brightness of a given star fo…

Cupid Is Not Doomed Yet: On the Stability of the Inner Moons of Uranus

Matija Ćuk, Robert S. French, Mark R. Showalter +2

Some of the small inner moons of Uranus have very closely-spaced orbits. Multiple numerical studies have found that the moons Cressida and Desdemona, within the Portia sub-group, a…

Frontiers in Planetary Rings Science

Shawn M. Brooks, Tracy M. Becker, K. Baillié +25

We now know that the outer solar system is host to at least six diverse planetary ring systems, each of which is a scientifically compelling target with the potential to inform us…

Dynamics of multiple bodies in a corotation resonance: Conserved quantities and relevance to ring arcs

Joseph A. A'Hearn, Matthew M. Hedman, Maryame El Moutamid

The interactions among objects in a mean motion resonance are important for the orbital evolution of satellites and rings, especially Saturn's ring arcs and associated moons. In th…

Dynamical phenomena at the inner edge of the Keeler gap

Radwan Tajeddine, Philip D. Nicholson, Matthew S. Tiscareno +3

We analyze several thousand Cassini ISS images in order to study the inner edge of the Keeler gap in Saturn's outer A ring. We find strong evidence for an m=32 perturbation with a…

Derivation of Capture Probabilities for the Corotation Eccentric Mean Motion Resonances

Maryame El Moutamid, Bruno Sicardy, Stéfan Renner

We study in this paper the capture of a massless particle into an isolated, first order Corotation Eccentric Resonance (CER), in the framework of the Planar, Eccentric and Restrict…
