论文摘要
关于太阳系彗星的原始或原始的问题是一个持续的争议。在这篇综述中,我们描述了彗星从太阳星云中的灰尘和冰晶粒到外部太阳系中的当代小体的物理演变。这包括尘埃聚集的阶段,地球的形成,它们的热进化和碰撞过程的结果。我们使用有关彗星的经验证据,尤其是从罗塞塔(Rosetta)任务到67p/churyumov-gerasimenko的彗星,以得出有关彗星可能的热和碰撞演化的结论。
Questions regarding how primordial or pristine the comets of the solar system are have been an ongoing controversy. In this review, we describe comets' physical evolution from dust and ice grains in the solar nebula to the contemporary small bodies in the outer solar system. This includes the phases of dust agglomeration, the formation of planetesimals, their thermal evolution and the outcomes of collisional processes. We use empirical evidence about comets, in particular from the Rosetta Mission to comet 67P/Churyumov--Gerasimenko, to draw conclusions about the possible thermal and collisional evolution of comets.
