Rings around irregular bodies. II. Numerical simulations of the 1/3 spin-orbit resonance confinement and applications to Chariklo
Heikki Salo, Bruno Sicardy
Rings have been found around Chariklo, Haumea and Quaoar, three small objects of the Solar System. All these rings are observed near the second-order spin-orbit resonances (SORs) 1…
Rings around irregular bodies I. Structure of the resonance mesh, applications to Chariklo, Haumea and Quaoar
Bruno Sicardy, Heikki Salo, Maryame El Moutamid +2
Three ring systems have been discovered to date around small irregular objects of the solar system (Chariklo, Haumea and Quaoar). For the three bodies, material is observed near th…
Viscous overstability in dense planetary rings -- Effect of vertical motions and dense packing
Marius Lehmann, Heikki Salo
We investigate the linear axisymmetric viscous overstability in dense planetary rings with typical values of the dynamical optical depth . We develop a granular flow…
Exploring overstabilities in Saturn's A ring using two stellar occultations
M. M. Hedman, P. D. Nicholson, H. Salo
Certain regions of Saturn's rings exhibit periodic opacity variations with characteristic radial wavelengths of up to a few hundred meters that have been attributed to viscous over…
