Footprints of a possible Ceres asteroid paleo-family
(2016-02-22)
Ceres is the largest and most massive body in the asteroid main belt. Observational data from the Dawn spacecraft reveal the presence of at least two impact craters about 280 km in diameter on the Ceres surface, that could ...
Chaotic diffusion caused by close encounters with several massive asteroids: II. the regions of (10) Hygiea, (2) Pallas, and (31) Euphrosyne
(2013-02-11)
Context. Close encounters with (1) Ceres and (4) Vesta, the two most massive bodies in the main belt, are known to be a mechanism of dynamical mobility able to significantly alter proper elements of minor bodies, and they ...

The influence of Ceres on the dynamical evolution of the Zdenekhorsky/Nemesis asteroid family
(2019-01-01)
The Nemesis family, also identified as the Zdenekhorsky family by some authors, is an “incomplete” asteroid family in the central main belt, characterized by an asymmetric distribution between its left and right side, with ...
Impactor flux and cratering on Ceres and Vesta: Implications for the early solar system
(EDP Sciences, 2011-10)
Context. The forthcoming arrival of the NASA's Dawn spacecraft to Ceres and Vesta means that these unexplored worlds in the asteroid main belt are targets of several studies. Aims. We study the impactor flux and cratering ...
On the Astrid asteroid family
(2016-09-11)
Among asteroid families, the Astrid family is peculiar because of its unusual inclination distribution. Objects at a ≃ 2.764 au are quite dispersed in this orbital element, giving the family a 'crab-like' appearance. Recent ...
The Hoffmeister asteroid family
(2017-01-01)
The Hoffmeister family is a C-type group located in the central main belt. Dynamically, it is important because of its interaction with the ν1C nodal secular resonance with Ceres, which significantly increases the dispersion ...
Detection of the Yarkovsky effect for C-type asteroids in the Veritas family
(Oxford Univ Press, 2017-08-01)
The age of a young asteroid family can be determined by tracking the orbits of family members backward in time and showing that they converge at some time in the past. Here we consider the Veritas family. We find that the ...
