论文摘要
为支持广泛持有的观念，即在富含碳富含碳的行星星云（PNE）中增强了不明身份的红外带（UIB）是一个显着的UIB7μm7μm，而C/O比率相关图是六个PNE，从空中观察获得的，并于1986年由M. Coolorks发行，这是一个了不起的UIB7μm，由M. 1986发行。但是，Cohen＆Barlow在2005年提出的太空数据降低了这种相关性，我表明它们较大的数据集提供了否认UIBS与PNE中的碳丰度之间的特定联系。从这些数据中，星际UIB载体不能起源于富含碳富含碳的pne的大气。
The concrete evidence adduced to support the widely held idea that unidentified infrared bands (UIBs) are enhanced in carbon-rich planetary nebulae (PNe) is a remarkable UIB 7.7 μm versus C/O ratio correlation plot for six PNe, obtained from air-born observations and published in 1986 by M. Cohen and coworkers. However, the space-born data presented by Cohen & Barlow in 2005 undercut this correlation, and I show that the larger dataset they provide disproves a specific link between UIBs and carbon abundance in PNe. It also follows from these data that interstellar UIB carriers cannot originate from the atmosphere of carbon-rich PNe.
