Dynamical Spreading of Asteroid Families by the Yarkovsky Effect.

Examines the dynamical spreading of asteroid families by the Yarkovsky effect. Ideas on the orbital distributions of and production of asteroid families; Effect of interactions between drifting asteroid family members and resonances can also produce unique eccentricity and inclination changes; Definition of Yarkovsky effect as a thermal radiation force that causes objects to undergo semimajor axis drift.
