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 ASTEROID BELT AS A RELIC from A CHAOTIC EARLY SOLAR SYSTEM
(2016-12-10)
The orbital structure of the asteroid belt holds a record of the solar system's dynamical history. The current belt only contains ∼10-3 Earth masses yet the asteroids' orbits are dynamically excited, with a large spread ...
Scattering V-type asteroids during the giant planet instability: a step for Jupiter, a leap for basalt
(Oxford Univ Press, 2017-06-01)
V-type asteroids are a taxonomic class whose surface is associated with a basaltic composition. The only known source of V-type asteroids in the Main Asteroid Belt is (4) Vesta, which is located in the inner part of the ...
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 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 ...
DETECTION of the YORP EFFECT for SMALL ASTEROIDS in the KARIN CLUSTER
(2016-06-01)
The Karin cluster is a young asteroid family thought to have formed only ≃ 5.75 Myr ago. The young age can be demonstrated by numerically integrating the orbits of Karin cluster members backward in time and showing the ...
Chaotic diffusion caused by close encounters with several massive asteroids The (4) Vesta case
(Edp Sciences S A, 2012-07-01)
Context. Close encounters with massive asteroids are known to be a mechanism of dynamical mobility that can significantly alter proper elements of minor bodies, and they are the main source of dynamical mobility for ...
