Chariklo is the only small solar system body confirmed to have rings. Given the instability of its orbit, the presence of rings is surprising, and their origin remains poorly understood. In this work, we study the dynamical history of the Chariklo system by integrating almost 36,000 Chariklo clones backward in time for 1 Gyr under the influence of the Sun and the four giant planets. By recording all close encounters between the clones and planets, we investigate the likelihood that Chariklo’s rings could have survived since its capture to the Centaur population. Our results reveal that Chariklo’s orbit occupies a region of stable chaos, resulting in its orbit being marginally more stable than those of the other Centaurs. Despite this, we find that it was most likely captured to the Centaur population within the last 20 Myr, and that its orbital evolution has been continually punctuated by regular close encounters with the giant planets. The great majority (>99%) of those encounters within 1 Hill radius of the planet have only a small effect on the rings. We conclude that close encounters with giant planets have not had a significant effect on the ring structure. Encounters within the Roche limit of the giant planets are rare, making ring creation through tidal disruption unlikely.read more

Simulations of the Population of Centaurs I: The Bulk Statistics
TL;DR: In this paper, large-scale simulations of the Centaur population are carried out, where the evolution of 23328 particles based on the orbits of 32 well-known Centaurs is followed for up to 3 Myr in the forward and backward direction under the influence of the 4 massive planets.

A hybrid symplectic integrator that permits close encounters between massive bodies
TL;DR: In this article, a mixed-variable symplectic integrator is proposed to solve the problem of the potential energy term for the pair undergoing the encounter becoming comparable to the terms representing the unperturbed motion in the Hamiltonian, which can be overcome using a hybrid method in which the close encounter term is integrated using a conventional integrator, whilst the remaining terms are solved symplectically.
The long-term dynamical behavior of short-period comets
TL;DR: In this article, it is shown that the anomalous concentration of the argument of perihelion of the Jupiter-family comets near 0 and 180 deg is a direct result of their aphelion distance being close to 5.2AU and the comet being recently perturbed onto a Jupiter- family orbit.
