Formation of the G-ring arc
(Oxford Univ Press, 2016-09-11)
Since 2004, the images obtained by the Cassini spacecraft's on-board cameras have revealed the existence of several small satellites in the Saturn system. Some of these small satellites are embedded in arcs of particles. ...
THE RINGS of CHARIKLO under CLOSE ENCOUNTERS with the GIANT PLANETS
(2016-06-20)
The Centaur population is composed of minor bodies wandering between the giant planets that frequently perform close gravitational encounters with these planets, leading to a chaotic orbital evolution. Recently, the discovery ...
Particles Co-orbital to Janus and to Epimetheus: A Firefly Planetary Ring
(2018-01-01)
The Cassini spacecraft found a new and unique ring that shares the trajectory of Janus and Epimetheus, co-orbital satellites of Saturn. Performing image analysis, we found this to be a continuous ring. Its width is between ...
Rings under close encounters with the giant planets: Chariklo versus Chiron
(2018-10-01)
In 2014, the discovery of two well-defined rings around the Centaur (10199) Chariklo was announced. This was the first time that such structures were found around a small body. In 2015, it was proposed that the Centaur ...
The dynamics of the outer edge of Saturn's A ring perturbed by the satellites Janus and Epimetheus
(2019-07-01)
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 of the horseshoe motion of the two ...
On the location of the ring around the dwarf planet Haumea
(2019-04-11)
The recently discovered ring around the dwarf planet (136108) Haumea is located near the 1:3 resonance between the orbital motion of the ring particles and the spin of Haumea. In the current work, we study the dynamics of ...
The role of Mab as a source for the mu ring of Uranus (Research Note)
(Edp Sciences S A, 2012-07-01)
Context. We previously analysed how the solar radiation force combined with the planetary oblateness changes the orbital evolution of a sample of dust particles located at the secondary ring system of Uranus. Both effects ...
Constraining the nature of the possible extrasolar PDS110b ring system
(2021-08-01)
The young star PDS110 in the Ori OB1a association underwent two similar eclipses in 2008 and 2011, each of which lasted for a period of at least 25 days. One plausible explanation for these events is that the star was ...
Neptune's ring arcs confined by coorbital satellites: Dust orbital evolution through solar radiation
(2020-06-11)
Here, we report the results of a set of numerical simulations of the system formed by Neptune, Galatea, dust ring particles, and hypothetical co-orbital satellites. This dynamical system depicts a recent confinement mechanism ...
