Confined tumbling state as the origin of the excess of slowly rotating asteroids
Wen-Han Zhou, Patrick Michel, Marco Delbo +4
The rotational distribution of asteroids as a function of their size is used {as a diagnostic of} their physical properties and evolution. Recent photometric surveys from the Gaia…

Diurnal temperature variation as the source of the preferential direction of fractures on asteroids: theoretical model for the case of Bennu
D. Uribe, M. Delbo, P. -O. Bouchard +1
It has been shown that temperature cycles on airless bodies of our Solar System can cause damaging of surface materials. Nevertheless, propagation mechanisms in the case of space o…
