Scientific paper

In this paper we present a comprehensive analysis of the dynamics in the region of the Veritas family, aiming to describe the principal mechanisms at work and provide a more reliable estimate of the diffusion rate. Our numerical integrations confirm previous results on the chaotic motion of the family members and on the resonances involved, but also indicate that the members of the family can be classified into four groups exhibiting different dynamical behavior. Using a numerical method, based on the integration of a large number of clones for each member, we calculate the diffusion coefficients in proper eccentricity and inclination. The diffusion rate provides an estimate for the age of the family, confirming that it must be comparatively young (~50 Myrs).
