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…
Stellar Occultations by Transneptunian objects: from Predictions to Observations and Prospects for the Future
J. L. Ortiz, B. Sicardy, J. I. B. Camargo +2
In terms of scientific output, the best way to study solar system bodies is sending spacecraft to make in-situ measurements or to observe at close distance. Probably, the second be…
The thermal emission of Centaurs and Trans-Neptunian objects at millimeter wavelengths from ALMA observations
E. Lellouch, R. Moreno, T. Müller +9
The sensitivity of ALMA makes it possible to detect thermal mm/submm emission from small/distant Solar System bodies at the sub-mJy level. Measured fluxes are primarily sensitive t…
Size and shape of Chariklo from multi-epoch stellar occultations
R Leiva, B Sicardy, J I B Camargo +28
We use data from five stellar occultations observed between 2013 and 2016 to constrain Chariklo's size and shape, and the ring reflectivity. We consider four possible models for Ch…
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…
