Abstract
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 is either 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 primarily explained the scientific
aspect of the implementation, while technical details will be made freely
available along with the source codes.
对于研究太阳系小天体的长期演化,在动力学模型中加入Yarkovsky和Yarkovsky- o 'Keefe-Radzievskii-Paddack (YORP)效应是至关重要的。然而,在公开可用的n体代码中实现这些效果要么是缺乏的,要么是使用非常简化的模型实现的。在本文中,我们提出了一个在汞和轨道n体代码中耦合Yarkovsky/YORP效应的实现。除了这两种影响,我们还包括了非破坏性碰撞和旋转引起的分裂的影响,以正确地模拟小行星的自旋状态。鉴于许多合并效应的随机性质,该软件适用于统计动力学研究。在这里,我们主要解释了实现的科学方面,而技术细节将与源代码一起免费提供。
