| Abstract: | The lack of asteroids in the 2/1-resonance is explained by the global stochasticity of the solutions in the Sun-Jupiter-Saturn-asteroid model. The explanation is based on data obtained with Laskar's frequency map analysis and on simulations showing the decisive influence of Jupiter's orbit perturbations related to the "Great Inequality". This revised version was published online in July 2006 with corrections to the Cover Date. |
