Dynamical environment and stability around Centaur (2060) Chiron
Gustavo Madeira, Bruno Morgado, Chrystian Pereira +3
A recent stellar occultation revealed that the Centaur (2060) Chiron hosts a broad disk extending beyond ~200 km from its centre, embedding three ring-like structures (Chi1R, Chi2R…
The rings of (2060) Chiron: Evidence of an evolving system
C. L. Pereira, F. Braga-Ribas, B. Sicardy +54
The centaur (2060) Chiron has long been a candidate for hosting material in orbit, based on occultation and photometric and spectroscopic data. Here, we present a multichord stella…
The resilience of the sailboat stable region
Rafael Sfair, Tiago F. L. L. Pinheiro, Giovana Ramon +1
Binary systems host complex orbital dynamics where test particles can occupy stable regions despite strong gravitational perturbations. The sailboat region, discovered in the Pluto…
Particle dynamics in TOI-178 planetary system
J. Boskovic, R. Sfair, C. M. Schäfer
The TOI-178 system hosts six planets with five of them locked in a :4:6:9:12 Laplace resonance chain. We perform N-body simulations to investigate the dynamics of test particles in…
Forming Mercury by a grazing giant collision involving similar mass bodies
Patrick Franco, Fernando Roig, Othon C. Winter +3
The origin of Mercury still remains poorly understood compared to the other rocky planets of the Solar System. One of the most relevant constraints that any formation model has to…
