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…
Hydrodynamical simulations of proto-Moon degassing
Gustavo Madeira, Leandro Esteves, Sebastien Charnoz +2
Similarities in the non-mass dependent isotopic composition of refractory elements with the bulk silicate Earth suggest that both the Earth and the Moon formed from the same materi…
Long-term dust dynamics in Didymos and Dimorphos system: production, stability, and transport
Gustavo Madeira, Sebastien Charnoz, Nicolas Rambaux +1
Target of NASA's DART mission, the system of Didymos and Dimorphos will once again be visited by a space mission -- ESA's Hera mission, scheduled to be launch in 2024. Hera will ar…
Revisiting Dimorphos formation: A pyramidal regime perspective and application to Dinkinesh's satellite
Gustavo Madeira, Sebastién Charnoz
Dimorphos' oblate shape challenges formation models. Landslides on Didymos, induced by YORP effect, probably created a debris ring from which Dimorphos would have formed. Nonethele…
