论文摘要
我们探索围绕KBO 2014 MU69（Arrokoth）的颗粒长期动态（月球，碎片，碎片等）的性质，以及围绕Kuiper带中可能存在的类似接触二进制对象。通过构建适当的稳定性图，以及通常基于开普勒地图理论的分析方法，研究了MU69山球内颗粒的混乱扩散（或通常是类似的物体）。研究了粒子云的形成和演变，由于山球内部的混乱扩散，估计了云的寿命。
We explore properties of the long-term dynamics of particles (moonlets, fragments, debris etc.) around KBO 2014 MU69 (Arrokoth), as well as around similar contact-binary objects potentially present in the Kuiper belt. The chaotic diffusion of particles inside the Hill sphere of MU69 (or, generally, a similar object) is studied by means of construction of appropriate stability diagrams and by application of analytical approaches generally based on the Kepler map theory. The formation and evolution of the particle clouds, due to the chaotic diffusion inside the Hill sphere, are studied and the cloud lifetimes are estimated.
