标题： Volatiles

摘要： 小天体是行星形成并迁移至当前位置时的剩余构建块。 它们的挥发性成分和相对丰度作为时间胶囊，记录了原太阳星云中的形成条件。 通过限制半人马座小天体的挥发性成分，我们可以填补理解我们太阳系历史的重要空白。 我们在此回顾小天体中挥发物的知识现状，影响小天体挥发性成分和活动的过程，以及未来可以利用的能力，以推进我们对半人马座小天体中挥发物的理解。 显示英文摘要

摘要： Small bodies are the remnant building blocks from the time when the planets formed and migrated to their current positions. Their volatile composition and relative abundances serve as time capsules for the formation conditions in the protosolar nebula. By constraining the volatile composition of Centaurs, we can fill in important gaps in understanding the history of our solar system. We review here the state of knowledge for volatiles in small bodies, processes that influence volatile composition and activity in small bodies, and future capabilities that can be leveraged to advance our understanding of volatiles in Centaurs.
