Dynamical implications of the recently detected feature around Quaoar and constraints on the presence of additional satellites
Gustavo Madeira, Leandro Esteves, Bruno E. Morgado +4
A recently reported opaque feature in the Quaoar system, detected during the 25 June 2025 stellar occultation, has been interpreted as either a 15 km-radius satellite or a dense, s…

On the formation of satellites in dense solid-particle disks
G. Madeira, L. Esteves, T. F. L. L. Pinheiro +3
Single massive satellites are of great observational interest, as they can produce prominent and potentially detectable signatures. For terrestrial planets and super-Earths, giant…

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…
