The Eos family halo

Original language description

We study K-type asteroids in the broad surroundings of the Eos family because they seem to be intimately related, according to their colours measured by the Sloan Digital Sky Survey. Such 'halos' of asteroid families have been rarely used as constraintsfor dynamical studies to date. We explain its origin as bodies escaping from the family 'core' due to the Yarkovsky semimajor-axis drift and interactions with gravitational resonances, mostly with the 9/4 mean-motion resonance with Jupiter at 3.03 AU. Our N-body dynamical model allows us to independently estimate the age of the family 1.5-1.9 Gyr. This is approximately in agreement with the previous age estimate by Vokrouhlicky et al. (2006) based on a simplified model (which accounts only for changes of semimajor axis). We can also constrain the geometry of the disruption event which had to occur at the true anomaly f similar or equal to 120-180.
