标题： Tidal interactions - crude body model in dynamical investigations

摘要： 本文介绍了对巨行星附近小天体动力学的研究结果。 我们使用了最简单的天体模型：受行星潮汐力作用的引力束缚、旋转接触双星。 此类双星的自转变化在行星近距离遭遇期间被广泛研究。 观察到两种主要的动力学行为：(i) 角速度的巨大但暂时波动，以及 (ii) 在近距离接近期间旋转的永久变化。 第一种类型主要出现在快速旋转体中，而第二种类型则出现在自转周期超过12小时的缓慢旋转物体群体中。 附上了关于这种粗略物理天体模型在动力学研究中的适用性以及与之前结果的比较的结论。 这些结果使我们能够提出一个论点，解释极端缓慢旋转体的形成现象以及这类物体的观测过剩。 显示英文摘要

摘要： The paper presents results of investigations of small bodies dynamics in a vicinity of giant planets. We used the most simple body model: gravitationally bounded, rotating contact binary affected by the tidal force acting from a planet. Spin variations of such binaries were extensively studied during planetary close encounters. Two main types of dynamical behaviour were observed: (i) huge but interim fluctuations of the angular velocity and (ii) permanent changes of a rotation during a close approach. The first type is observed mainly for fast rotators, while the second one was encountered in a population of slowly spinning objects with periods longer than 12 hours. Conclusions on usability of such crude physical body models in dynamical investigations and a comparison to previous results were attached. The results allow us to formulate a thesis explaining the phenomenon of creation of the extremely slow rotators and an observational excess of such type of objects.
