n体问题的新周期轨道

New Periodic Orbits for the n-Body Problem

Cristopher Moore, Michael Nauenberg

AI总结:

通过最小化作用量函数,数值发现了具有立方对称性的三维n体周期轨道,并验证了平面3体轨道的动态稳定性。

摘要:

自从发现三体问题的8字形轨道[Moore 1993]以来,大量具有等质量和优美对称性的n体问题周期轨道被发现。然而,文献中出现的多数轨道要么是平面的,要么是通过扰动平面轨道得到的。这里我们展示了一些新的具有等质量和立方对称性的三维周期n体轨道。我们通过最小化作为轨迹傅里叶系数函数的作动量数值发现了这些轨道。我们还给出了数值证据,表明最初由[Hénon, 1976]发现、由[Moore 1993]重新发现、并由[Nauenberg 2001]发现存在于不同质量下的一个平面三体轨道是动态稳定的。谨以此文敬献给Philip Holmes。

英文摘要:

Since the discovery of the figure-8 orbit for the three-body problem [Moore 1993] a large number of periodic orbits of the n-body problem with equal masses and beautiful symmetries have been discovered. However, most of those that have appeared in the literature are either planar or are obtained from perturbations of planar orbits. Here we exhibit a number of new three-dimensional periodic n-body orbits with equal masses and cubic symmetry. We found these orbits numerically by minimizing the action as a function of the trajectories' Fourier coefficients. We also give numerical evidence that a planar 3-body orbit first found in [Hénon, 1976], rediscovered by [Moore 1993], and found to exist for different masses by [Nauenberg 2001], is dynamically stable. It is a pleasure to dedicate this paper to Philip Holmes.
