中文摘要
空间中几乎所有物体的红外光谱都以大碳分子(即多环芳烃)的强发射特征为主。 作为一类,多环芳烃是空间中已知的最复杂和最丰富的分子,在各种过程中发挥着至关重要的作用,如其他元素的丰度,星际介质的冷却和加热等,此外,它们很可能在生命的前生物进化中发挥了重要作用。因此,研究这些巨大而丰富的星际分子,它们的形成和演化以及控制它们丰度的天体生物学过程,对于我们理解我们周围的宇宙和我们的宇宙根源具有非常重要的意义。
英文摘要
The infrared spectra of almost all objects in space are dominated by strong emission features due to large carbonaceous molecules, i.e. Polycyclic Aromatic Hydrocarbons (PAHs). As a class, PAHs are the most complex and most abundant molecules known in space and play a crucial role in various processes such as the abundances of other elements, the cooling and heating of the interstellar medium etc. In addition, they may well have played an important role in the prebiotic evolution of life. Hence, studying these large, abundant interstellar molecules, their formation and evolution and the astrobiological processes that control their abundance is of tremendous importance for our understanding of the universe around us and our cosmic roots.
