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…
Machine learning approach for mapping the stable orbits around planets
Tiago F. L. L. Pinheiro, Rafael Sfair, Giovana Ramon
Numerical N-body simulations are commonly used to explore stability regions around exoplanets, offering insights into the possible existence of satellites and ring systems. This st…
