Studies of Diffuse Interstellar Bands. V. Pairwise Correlations of Eight Strong DIBs and Neutral Hydrogen, Molecular Hydrogen, and Color Excess
ISM lines and bands − ISM molecules
2010/11/15
We establish correlations between equivalent widths of eight diffuse interstel-lar bands (DIBs), and examine their correlations with atomic hydrogen, molec-ular hydrogen, and EB−V . The DIBs are...

2010/11/9
We present strong evidence that the broad, di use interstellar bands (DIBs) at 4881 and
5450A are caused by the B 1B1 X 1A1 transition of H2CCC (l-C3H2). The large widths of the
bands are due to th...

We present the largest sample to-date of intermediate-resolution blue-to-red optical spectra of B-type supergiants in M31 and undertake the first survey of diffuse interstellar bands (DIBs) in this ga...
