Introduction: Radio observations of long-period comet C/2016 R2 (PanSTARRS) revealed that it was remarkably depleted in water (Biver et al. 2018). The spectrum was instead dominated by bands of CO+ and N2+, rarely seen in such abundance in comets bef

Comet C/2016 R2 PanSTARRS (hereafter C/2016 R2) presents an unusually high N2/CO abundance ratio, as well as a heavy depletion in H2O, making it the only known comet of its kind. Understanding its dynamical history is therefore of essential importanc

During the thirteen years in orbit around Saturn before its final plunge, the Cassini spacecraft provided more than ten thousand astrometric measurements. Such large amounts of accurate data enable the search for extremely faint signals in the orbita

International audience; This study is a companion paper to (Baillié et al. 2019), in which we showed that a past episode of inward migration of Mimas could have created the Cassini Division. We here investigate the possible causes of this inward mig

A Hamiltonian model is constructed for the spin axis of a planet perturbed by a nearby planet with both planets in orbit about star. We expand the planet-planet gravitational potential perturbation to first order in orbital inclinations and eccentric
