Unassigned Broad and Narrow Diffuse Interstellar Bands Observed in Dust-obscured B-stars

This study by P. Reig, I. Negueruela, J. Fabregat, R. Chato, and M. J. Coe presents observations of 5 B-stars lightly obscured by dust in interstellar clouds. Over 200 Diffuse Interstellar Bands (DIBs) are known, but none have been assigned yet. Narrower DIBs are identified by wavelength, with a broad DIB centered at 5778Å. Other spectral lines arise in the stars' atmospheres.

  2. Over 200 DIBs are now known and not one has yet been assigned! P. Reig, I. Negueruela, J. Fabregat, R. Chato and M. J. Coe

  3. 5 B-stars, each lightly obscured by dust in single interstellar clouds. Narrower DIB are identified by wavelength. A broad DIB centred at 5778Å. Other lines arise in the stars’ atmospheres.
