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 ...
The empty primordial asteroid belt
(Amer Assoc Advancement Science, 2017-09-01)
The asteroid belt contains less than a thousandth of Earth's mass and is radially segregated, with S-types dominating the inner belt and C-types the outer belt. It is generally assumed that the belt formed with far more ...
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 ...

Dynamical evolution of V-type asteroids in the central main belt
(Oxford University Press, 2014-04-01)
The origin of this large population of V-type objects is not well understood. Since it seems unlikely that Vestoids crossing the 3J:-1A mean-motion resonance with Jupiter could account for the whole population of V-type ...
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 ...
The asteroid belt outer region under jumping-Jupiter migration
(Oxford Univ Press, 2017-09-01)
The radial configuration of the outer region of the main asteroid belt is quite peculiar, and has much to say about the past evolution of Jupiter. In this work, we investigate the dynamical effects of a jumping-Jupiter-like ...
Influence of the Centaurs and TNOs on the main belt and its families
(2016-12-01)
Centaurs are objects whose orbits are found between those of the giant planets. They are supposed to originate mainly from the Trans-Neptunian objects, and they are among the sources of Near-Earth Objects. Trans-Neptunian ...
