Abstract In 2019 it was exactly 100 years ago that the first two DIBs, diffuse interstellar bands, were discovered by Mary Lea Heger. Today some 500 + DIBs are known. In numerous observational, modelling and laboratory studies, efforts have been made to identify the carriers of these absorption features that are observed in the light of reddened stars crossing diffuse and translucent clouds. Despite several claims over the years that specific DIBs could be assigned to specific species, not one of these withstood dedicated follow-up studies. An exception is C 60 + . In 2015, Campbell et al. showed that two strong bands, recorded in the laboratory around 960 nm, coincided precisely with known DIBs and in follow-up studies three more matches between C 60 + transitions and new observational DIB studies were claimed. Over the last four years the evidence for C 60 + as the first identified DIB carrier – including new laboratory data and Hubble Space Telescope observations – has been accumulating, but not all open issues have been solved yet. This article summarizes 6 spectroscopic achievements that sequentially contributed to what seems to become the first DIB story with a happy end.

C60+作为漫射星际带载体 6幕光谱故事

摘要 在 2019 年，Mary Lea Heger 发现了前两个 DIB，即弥漫性星际带，正好是 100 年前。今天，已知大约有 500 多个 DIB。在大量的观测、建模和实验室研究中，已经努力确定这些吸收特征的载体，这些特征是在穿过漫射和半透明云的变红恒星的光线下观察到的。尽管多年来有一些声称可以将特定的 DIB 分配给特定的物种，但没有一个能够经受住专门的后续研究。一个例外是 C 60 +。2015 年，坎贝尔等人。表明在实验室中记录的 960 nm 附近的两个强带与已知的 DIB 精确重合，并且在后续研究中，声称 C 60 + 跃迁与新的观察性 DIB 研究之间的另外三个匹配。在过去四年中，C 60 + 作为第一个确定的 DIB 载体的证据——包括新的实验室数据和哈勃太空望远镜观测——已经在积累，但并非所有悬而未决的问题都已得到解决。这篇文章总结了 6 项光谱成就，它们依次促成了似乎成为第一个幸福结局的 DIB 故事。
