Figure 2: Orbital evolution on an (a, e) plane. The plotted data cover from -1 Myr to +1 Myr. For convenience, the planet-crossing curves are also shown. For drawing these curves, we assume that the Centaur and giant planets are moving on a common plane and the planetary eccentricities are fixed to the present values. |

Figure 5: Orbital evolution of other Centaurs near the resonant candidates. We plot the evolutional tracks on an (a, e) plane for the next 50 000 years. These objects are not wandering around so much on the (a, e) plane, in contrast to other Centaurs which have eccentric and/or planet-crossing orbits. Large orbital changes in the elements of 1994TA occur after the resonance is unlocked. The present orbital inclinations (unit: degree) are also indicated in parentheses. |
