Diffuse Interstellar Bands in 49 stars

We relate the equivalent widths of 11 diffuse interstellar bands, measured in the spectra of 49 stars, to different colour excesses in the ultraviolet. We find that most of the...本研究将49颗恒星光谱中测得的11条弥散星际带（diffuse interstellar bands）的等效宽度，与紫外波段的不同色余进行关联分析。我们发现，其中多数……
