Terrestrial planet formation constrained by mars and the structure of the asteroid belt
(2015-01-01)
Reproducing the large Earth/Mars mass ratio requires a strong mass depletion in solids within the protoplanetary disc between 1 and 3 au. The Grand Tack model invokes a specific migration history of the giant planets to ...
Taxonomy of asteroids in the Cybele region from the analysis of the Sloan Digital Sky Survey colors
(Elsevier, 2010-04)
In this paper we search for photometric data of asteroids in the outer region of the Hecuba gap in the Moving Object Catalogue of the Sloan Digital Sky Survey to find the spectrophotometric characteristics of small members ...
On the oldest asteroid families in the main belt
(2016-03-17)
Asteroid families are groups of minor bodies produced by high-velocity collisions. After the initial dispersions of the parent bodies fragments, their orbits evolve because of several gravitational and non-gravitational ...
Dynamical evolution of the Cybele asteroids
(2015-01-01)
The Cybele region, located between the 2J:-1A and 5J:-3A mean-motion resonances, is adjacent and exterior to the asteroid main belt. An increasing density of three-body resonances makes the region between the Cybele and ...
An interstellar origin for Jupiter's retrograde co-orbital asteroid
(2018-06-11)
Asteroid (514107) 2015 BZ509 was discovered recently in Jupiter's co-orbital region with a retrograde motion around the Sun. The known chaotic dynamics of the outer Solar system have so far precluded the identification of ...
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 ...
Dynamical evolution of V-type photometric candidates in the outer main belt
(Oxford Univ Press, 2014-11-01)
V-type asteroids, characterized by two absorption bands at 1.0 and 2.0 mu m, are usually thought to be portions of the crust of differentiated or partially differentiated bodies. Most V-type asteroids are found in the inner ...
The Zelima asteroid family: Resonant configuration and rotational fission clusters
(2020-03-01)
Asteroid families are groups of asteroids that are identifiable in domains of proper elements. They may be the outcome of a collision, or the product of rotational fission. Among collisional families, young asteroid families ...
Chirikov diffusion in the asteroidal three-body resonance (5, −2, −2)
(Springer, 2010-09)
The theory of diffusion in many-dimensional Hamiltonian system is applied to asteroidal dynamics. The general formulation developed by Chirikov is applied to the Nesvorný-Morbidelli analytic model of three-body (three-orbit) ...
Identification and dynamical properties of asteroid families
(2015-01-01)
Asteroids formed in a dynamically quiescent disk but their orbits became gravitationally stirred enough by Jupiter to lead to high-speed collisions. As a result, many dozen large asteroids have been disrupted by impacts ...
