The goal of this project is to probe the nature and origin of the Hilda asteroids comma a population of small bodies with orbits in stable mean-motion resonance with Jupiter. We will accomplish this objective by observing and characterizing the physical properties of quasi-Hilda objects comma an unstable population hidden among the Hildas.We selected observational targets based on the dynamical study of objects close to Hilda region. Our analysis show that these quasi-Hilda objects are probable Centaur interlopers that migrated inward comma temporally residing near the Hildas. We will monitor these objects for low-level activity and acquire their optical colors. Comparison between properties of these groups will provide valuable information about the surface of evolution of Centaurs when placed in a Hilda environment comma which will enable us to distinguish if Hildas and Centaurs can share a similar origin comma as proposed by dynamical models for the formation and evolution of the solar system.
