Didymos is a binary near-Earth asteroid. It is the target of the DART and HERA space
missions. The primary body, Didymos, rotates close to the spin at which it is expected to …

Ring arcs are the result of particles in corotation resonances with nearby satellites. Arcs are
present in Saturn and Neptune systems, in Saturn they are also associated with small …

In this work we analyse the orbital evolution and dynamical stability in the vicinity of the
small Saturnian moons Aegaeon, Methone, Anthe, and Pallene. We numerically resolve the …

ABSTRACT The arcs of Neptune–Fraternité, Egalité, Liberté, and Courage–are four
incomplete rings immersed in the Adams ring. A recent confinement model for the arcs …

Abstract Aegaeon (S/2008 S 1) is the last satellite discovered by the Cassini spacecraft at
the end of the 2000 s. Like the satellites Methone and Anthe, it is involved in mean motion …

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 …

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 …

The ring system and small satellites of Neptune were discovered during Voyager 2 flyby in
1989 (Smith et al. in Science 246: 1422, 1989). In this work we analyse the diffusion maps …

The interactions among objects in a mean motion resonance are important for the orbital
evolution of satellites and rings, especially Saturn's ring arcs and associated moons. In this …

Planetary rings, a common feature around giant planets, have recently been discovered
around centaurs and dwarf planets. These rings often contain azimuthally confined …
