Asteroid families in the first-order resonances with Jupiter

Abstract

We revise current populations of objects in the J2/1, J3/2 and J4/3 resonances. Two asteroid families, Schubart and Hilda, were discovered in the 3/2 mean motion resonances with Jupiter.

Using N-body numerical simulations we prove that the Yarkovsky effect (infrared thermal emission from the surface of asteroids) causes a systematic drift in eccentricity for resonant objects.
