Inclination of Miranda as a Constraint on the Tidal Dissipation of Uranus
Maryame El Moutamid, Matija Ćuk
The five major moons of Uranus record a complicated geological history characterized by both tectonic resurfacing and heavy impact cratering, connecting their evolution to dynamica…
Rings around irregular bodies I. Structure of the resonance mesh, applications to Chariklo, Haumea and Quaoar
Bruno Sicardy, Heikki Salo, Maryame El Moutamid +2
Three ring systems have been discovered to date around small irregular objects of the solar system (Chariklo, Haumea and Quaoar). For the three bodies, material is observed near th…
Origins of rings in the solar system
Bruno Sicardy, Maryame El Moutamid, Stefan Renner +2
Until about a decade ago, ring systems were only known to exist around giant planets. Each one of the four giant planets harbours its own distinctive and unique system of rings and…
Constraints on the structure and seasonal variations of Triton's atmosphere from the 5 October 2017 stellar occultation and previous observations
J. Marques Oliveira, B. Sicardy, A. R. Gomes-Júnior +234
A stellar occultation by Neptune's main satellite, Triton, was observed on 5 October 2017 from Europe, North Africa, and the USA. We derived 90 light curves from this event, 42 of…
The dynamics of rings around Centaurs and Trans-Neptunian Objects
Bruno Sicardy, Stefan Renner, Rodrigo Leiva +4
Since 2013, dense and narrow rings are known around the small Centaur object Chariklo and the dwarf planet Haumea. Dense material has also been detected around the Centaur Chiron,…
What confines the rings of Saturn?
Radwan Tajeddine, Philip D. Nicholson, Pierre-Yves Longaretti +2
The viscous spreading of planetary rings is believed to be counteracted by satellite torques, either through an individual resonance or through overlapping resonances. For the A ri…
Origin of the chaotic motion of the Saturnian satellite Atlas
S. Renner, N. J. Cooper, M. El Moutamid +4
We revisit the dynamics of Atlas. Using Cassini ISS astrometric observations spanning February 2004 to August 2013, Cooper et al. (2015) found evidence that Atlas is currently pert…
How Janus' Orbital Swap Affects the Edge of Saturn's A Ring?
Maryame El Moutamid, Philip D. Nicholson, Richard G. French +6
We present a study of the behavior of Saturn's A ring outer edge, using images and occultation data obtained by the Cassini spacecraft over a period of 8 years from 2006 to 2014. M…
A ring system detected around the Centaur (10199) Chariklo
F. Braga-Ribas, B. Sicardy, J. L. Ortiz +61
Until now, rings have been detected in the Solar System exclusively around the four giant planets. Here we report the discovery of the first minor-body ring system around the Centa…
Coupling between corotation and Lindblad resonances in the elliptic planar three-body problem
Maryame El Moutamid, Bruno Sicardy, Stéfan Renner
We investigate the dynamics of two satellites with masses and orbiting a massive central planet in a common plane, near a first order mean motion resonance +1: (…
Influence of the coorbital resonance on the rotation of the Trojan satellites of Saturn
Philippe Robutel, Nicolas Rambaux, Maryame El Moutamid
The Cassini spacecraft collects high resolution images of the saturnian satellites and reveals the surface of these new worlds. The shape and rotation of the satellites can be dete…
