We study long-term orbital evolution of resonant families among Hildas (located in the 3/2 resonance with Jupiter) and Trojans (in J1/1). The systematic drift in eccentricity, due to the Yarkovsky effect, enables us to determine their ages. We present a novel `(e,H) method', which exploits not only the overall spread in eccentricity, but also the distribution of family members in the plane eccentricity vs absolute magnitude.
We further describe a strong destabilisation of Hildas during the 1:2 Jupiter-Saturn resonance crossing (as described by the Nice model) and we estimate a re-population efficiency of the J2/1 and J3/2 regions from the adjacent main belt and planetesimal disk with respect to various migration rates.
