Building the Galilean moons system via pebble accretion and migration: A primordial resonant chain
(2021-06-01)
The origins of the Galilean satellites - namely Io, Europa, Ganymede, and Callisto - is not fully understood yet. Here we use N-body numerical simulations to study the formation of Galilean satellites in a gaseous ...
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 ...
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 ...
ORBITAL PERTURBATIONS OF THE GALILEAN SATELLITES DURING PLANETARY ENCOUNTERS
(Iop Publishing Ltd, 2014-08-01)
The Nice model of the dynamical instability and migration of the giant planets can explain many properties of the present solar system, and can be used to constrain its early architecture. In the jumping-Jupiter version ...
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 ...

Long-term dynamical evolution of Pallene (Saturn XXXIII) and its diffuse, dusty ring
(Oxford Univ Press, 2022-03-21)
The distinctive set of Saturnian small satellites, Aegaeon, Methone, Anthe, and Pallene, constitutes an excellent laboratory to understand the evolution of systems immersed in co-orbital dusty rings/arcs, subjected to ...
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 ...
