论文摘要
碰撞是塑造行星系统的关键过程之一。小行星家族是在我们的太阳系中仍然可以识别出的这种碰撞的结果。这些家庭为灾难性的破坏现象提供了独特的看法，并一直处于行星科学家的重点一个多世纪。他们中的大多数位于主带，火星和木星之间的小行星环。在这里，我们回顾这些家庭的基本特性，讨论最近的一些进展，并预测未来的挑战。这篇评论更加关注动态方面，例如家庭认同，确定年龄和长期演变。然而，文本超出了这一点。尤其是，我们介绍了年轻家庭的细节，这些细节在过去几年中取得了重大进展，我们预计将来它将发展得更快。我们还讨论了小行星家族在小行星带中的水冰含量的相关性，以及我们目前对家庭与主皮彗星之间联系的知识。
Collisions are one of the key processes shaping planetary systems. Asteroid families are outcomes of such collisions still identifiable across our solar system. The families provide a unique view of catastrophic disruption phenomena and have been in the focus of planetary scientists for more than a century. Most of them are located in the main belt, a ring of asteroids between Mars and Jupiter. Here we review the basic properties of the families, discuss some recent advances, and anticipate future challenges. This review pays more attention to dynamic aspects such as family identification, age determination, and long-term evolution. The text, however, goes beyond that. Especially, we cover the details of young families that see the major advances in the last years, and we anticipate it will develop even faster in the future. We also discuss the relevance of asteroid families for water-ice content in the asteroid belt and our current knowledge on links between families and main-belt comets.
