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 ...
THE RINGS of CHARIKLO under CLOSE ENCOUNTERS with the GIANT PLANETS
(2016-06-20)
The Centaur population is composed of minor bodies wandering between the giant planets that frequently perform close gravitational encounters with these planets, leading to a chaotic orbital evolution. Recently, the discovery ...
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 ...
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 ...
Nebular gas drag and planetary accretion with eccentric high-mass planets
(2013-04-08)
Aims.We investigate the dynamics of pebbles immersed in a gas disk interacting with a planet on an eccentric orbit. The model has a prescribed gap in the disk around the location of the planetary orbit, as is expected for ...
