quence solar mass loss on the stability of planetary orbits， they performed many integrations covering up to ～1011 yr of the orbital motions of the four jovian planets. the initial orbital elements and masses of planets are the same as those of our solar system in duncan & lissauer's paper， but they decrease the mass of the sun gradually in their numerical experiments. this is because they consider the effect of post-main-sequence solar mass loss in the paper. consequently， they found that the crossing time-scale of planetary orbits， which can be a typical indicator of the instability time-scale， is quite sensitive to the rate of mass decre
