The rings of Neptune
Imke de Pater, Stéfan Renner, Mark R. Showalter +1
In 1984, three telescopes in South America recorded an occultation of a star near Neptune. It was attributed to the existence of a partial ring or ring arc. The existence of ring a…
The dynamics of the outer edge of Saturn's A ring perturbed by the satellites Janus and Epimetheus
N. C. S. Araujo, S. Renner, N. J. Cooper +4
We present an analytical model to study the dynamics of the outer edge of Saturn's A ring. The latter is influenced by 7:6 mean motion resonances with Janus and Epimetheus. Because…
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,…
Ring dynamics around non-axisymmetric bodies with application to Chariklo and Haumea
B. Sicardy, R. Leiva, S. Renner +4
Dense and narrow rings have been discovered recently around the small Centaur object Chariklo and the dwarf planet Haumea, while being suspected around the Centaur Chiron. They are…
The structure of Chariklo's rings from stellar occultations
D. Bérard, B. Sicardy, J. I. B. Camargo +79
Two narrow and dense rings (called C1R and C2R) were discovered around the Centaur object (10199) Chariklo during a stellar occultation observed on 2013 June 3. Following this disc…
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…
