Abstract

Carbon because of its electronic structure can formulate several types of bonds and allotropes. In the ranking of elements in the Universe, carbon is the fourth most abundant after H, He and O. To date, carbon signatures have been detected in different parts of the interstellar medium (ISM), circumstellar medium (CSM) and in our solar system. It is now evident that in the ISM, carbon is present in the form of gas, ice and dust phases. Almost a decade ago, astronomers were able to trace the signature of the largest carbonaceous molecule, fullerene in different parts of the ISM, including planetary nebula (PNe), reflection nebula, and in ionised hydrogen (HII) regions. This has led the growing international astrochemistry community to revisit the formation pathways of different carbon nanostructures under simulated interstellar conditions. The aim of this article is to review and summarise all the experiments relevant to the formation of interstellar carbonaceous dust performed by various groups across the globe.

星际碳尘及其形成途径的实验天体化学研究
碳由于其电子结构可以形成几种类型的键和同素异形体。在宇宙元素的排名中,碳是仅次于H、He和O的第四丰富元素。迄今为止,在星际介质(ISM)、星周介质(CSM)和太阳系的不同部分都检测到了碳特征。现在很明显,在ISM中,碳以气体、冰和灰尘相的形式存在。大约十年前,天文学家能够在ISM的不同部分追踪到最大的碳质分子富勒烯的特征,包括行星星云(PNe)、反射星云和电离氢(HII)区域。这使得越来越多的国际天体化学界重新审视了在模拟星际条件下不同碳纳米结构的形成途径。本文的目的是回顾和总结全球各团体进行的与星际碳质尘埃形成相关的所有实验。

期刊介绍: Started in 1914 as the second scientific journal to be published from India, the Journal of the Indian Institute of Science became a multidisciplinary reviews journal covering all disciplines of science, engineering and technology in 2007. Since then each issue is devoted to a specific topic of contemporary research interest and guest-edited by eminent researchers. Authors selected by the Guest Editor(s) and/or the Editorial Board are invited to submit their review articles; each issue is expected to serve as a state-of-the-art review of a topic from multiple viewpoints.
