V-type asteroids are a taxonomic class whose surface is associated to a basaltic composition. The only known source of V-type asteroids in the Main Asteroid Belt is (4) Vesta, that is located in the inner part of the belt. However, many V-type astero

International audience; Many asteroid families are identified and well characterized all over the main asteroid belt. Interestingly, however, none of them are older than 4 Gyr. Many mechanisms have been proposed to disperse such old primordial astero

Dynamical formation of detached trans-Neptunian objects close to the 2:5 and 1:3 mean motion resonances with Neptune

Autor: Rodney S. Gomes, J. S. Soares, P. I. O. Brasil

Through a semi-analytic approach of the Kozai resonance inside an MMR, we show phase diagrams (e,��) that suggest the possibility of a scattered particle, after being captured in an MMR with Neptune, to become a detached object. We ran several nu

DYNAMICAL IMPLANTATION OF OBJECTS IN THE KUIPER BELT

Autor: David Nesvorný, P. I. O. Brasil, Rodney S. Gomes

Publikováno v: The Astronomical Journal. 148:56

Several models have been suggested in the past to describe the dynamical formation of hot Kuiper Belt objects (hereafter Hot Classicals or HCs for short). Here, we discuss a dynamical mechanism that allows orbits to evolve from the primordial planete
