Dominant factors for escape after the first triple-encounter are searched for in the three-body problem with zero initial
velocities and equal masses. By a global numerical survey on the whole initial-value space, it is found that not only a triple-collision
orbit but also a particular family of binary-collision orbits exist in the set of escape orbits. This observation is justified
from various viewpoints. Binary-collision orbits experiencing close triple-encounter turn out to be close to isosceles orbits
after the encounter and hence lead to escape. Except for a few cases, binary-collision orbits of near-isosceles slingshot
also escape.

A numerical procedure is devised to find binary collision orbits in the free-fall three-body problem. Applying this procedure, families of binary collision orbits are found and a sequence of triple collision orbits are positioned. A property of sets of binary collision orbits which is convenient to search triple collision orbits is found. Important numerical results are formulated and summarized in the final section. 相似文献

In the free‐fall three‐body problem, distributions of escape, binary, and triple collision orbits are obtained. Interpretation
of the results leads us to the existence of oscillatory orbits in the planar three‐body problem with equal masses. A scenario
to prove their existence is described.

The existence of escape and nonescape orbits arbitrarily close to the homothetic equilateral triplecollision orbit is considered analytically in the threebody problem with zero initial velocities and equal masses. It is proved that escape orbits in the initial condition space are distributed around three kinds of isosceles orbits. It is also proved that nonescape orbits are distributed in between the escape orbits where different particles escape. In order to show this, it is proved that the homotheticequilateral orbit is isolated from other triplecollision orbits as far as the collision at the first triple encounter is concerned. Moreover, the escape criterion is formulated in the planarisosceles problem and translated into the words of regularizing variables. The result obtained by us explains the orbital structure numerically. 相似文献
