论文摘要
为了研究小型太阳系对象的长期演变，在动态模型中添加Yarkovsky和Yarkovsky-O'Keefe-Radzievskii-Paddack（Yorp）效应是至关重要的。尽管如此，这些效果在公开可用的N体制代码中的实现通常仍缺乏，或者使用显着简化的模型实现了效果。在本文中，我们介绍了在水星和Orbfit $ n $体代码中耦合Yarkovsky/Yorp效果的实现。除了这两种效果外，我们还包括了非破坏性碰撞和旋转诱导的分裂的影响，以正确对小行星自旋状态进行建模。鉴于许多合并效应的随机性，该软件适用于统计动力学研究。在这里，我们解释了实施的科学方面，同时将与源代码一起免费提供技术细节。
For studies of the long-term evolution of small Solar System objects, it is fundamental to add the Yarkovsky and Yarkovsky-O'Keefe-Radzievskii-Paddack (YORP) effects in the dynamical model. Still, implementations of these effects in publicly available N-body codes are often lacking, or the effects are implemented using significantly simplified models. In this paper, we present an implementation of the coupled Yarkovsky/YORP effects in the mercury and OrbFit $N$-body codes. Along with these two effects, we also included the effects of non-destructive collisions and rotationally induced breakups to model the asteroid spin state properly. Given the stochastic nature of many incorporated effects, the software is suitable for statistical dynamical studies. Here we explained the scientific aspect of the implementation, while technical details will be made freely available along with the source codes.
