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…

Rapid formation of binary asteroid systems post rotational failure: a recipe for making atypically shaped satellites
John Wimarsson, Zhen Xiang, Fabio Ferrari +4
Binary asteroid formation is a highly complex process, which has been highlighted with recent observations of satellites with unexpected shapes, such as the oblate Dimorphos by the…
