论文摘要
本文提供了与恒星和行星形成相关的星体化学的简要摘要和概述。它针对该领域的新研究人员，使他们能够快速概述这个快速发展的地区的景观和关键文献。描述了分子从云到原始信封，磁盘和最终系外行星大气的旅程。强调，气体和冰的化学之间的密切关系以及形成行星磁盘的物理结构和演变的重要性，包括谷物的生长和漂移以及在尘埃陷阱处的元素锁定。因此，使用元素丰富的比率（例如c/o，c/n，o/h）在外部球星大气中将它们链接到其地层位点并不简单。有趣的线索来自我们自己的太阳系中的陨石和彗星以及地球的组成。一个新的边界是对分子线运动学的分析，以检测磁盘中的年轻行星。未来几年要解决的许多主要问题得到了提出，并强调了挑战和机遇。
This paper provides a brief summary and overview of the astrochemistry associated with the formation of stars and planets. It is aimed at new researchers in the field to enable them to obtain a quick overview of the landscape and key literature in this rapidly evolving area. The journey of molecules from clouds to protostellar envelopes, disks and ultimately exoplanet atmospheres is described. The importance of the close relation between the chemistry of gas and ice and the physical structure and evolution of planet-forming disks, including the growth and drift of grains and the locking up of elements at dust traps, is stressed. Using elemental abundance ratios like C/O, C/N, O/H in exoplanetary atmospheres to link them to their formation sites is therefore not straightforward. Interesting clues come from meteorites and comets in our own solar system, as well as from the composition of Earth. A new frontier is the analysis of the kinematics of molecular lines to detect young planets in disks. A number of major questions to be addressed in the coming years are formulated, and challenges and opportunities are highlighted.
