The first observed stellar occultations by the irregular satellite (Saturn IX) Phoebe and improved rotational period
A. R. Gomes-Júnior, M. Assafin, F. Braga-Ribas +24
We report six stellar occultations by (Saturn IX) Phoebe, an irregular satellite of Saturn, obtained between mid-2017 and mid-2019. The 2017 July 06 event is the first stellar occu…
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 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,…
Pluto's ephemeris from ground-based stellar occultations (1988-2016)
J. Desmars, E. Meza, B. Sicardy +13
From 1988 to 2016, several stellar occultations have been observed to characterize Pluto's atmosphere and its evolution (Meza et al, 2019). From each stellar occultation, an accura…
