论文摘要
小行星和彗星之间的实际区别，被视为雪线两侧的增生产物，比以前所理解的更清晰。在本章中，我们讨论了众多的太阳系人群，这些太阳系人群具有与其性质和起源的任何简单诊断相冲突的物理和动力学特性。对这些所谓的“连续性”或“过渡对象”的研究，包括太阳系中许多最有趣的物体，对从彗星的消亡以及小行星的激活到产生星际间碎屑和陆地行星的产生的广泛科学主题具有影响。我们概述了有关小行星 - 柱连续体的当前知识状态，并讨论了太阳系中小体显示的活动背后的许多物理过程。
The practical distinctions between asteroids and comets, viewed as products of accretion on either side of the snow line, are less clear-cut than previously understood. In this chapter, we discuss the numerous solar system populations which have physical and dynamical properties that conflict with any simple diagnosis of their nature and origin. Studies of these so-called "continuum" or "transition objects", which include many of the most intriguing bodies in the solar system, have implications for a broad range of scientific topics from the demise of comets and the activation of asteroids to the production of interplanetary debris and the origin of the terrestrial planet volatiles. We present an overview of the current state of knowledge concerning the asteroid-comet continuum and discuss the numerous physical processes behind the activity shown by small bodies in the solar system.
