A Possible New Sequence of DIBs
Abstract
One of the key factors in explaining nature of DIB carriers is to find regularities in their spectrum. Such a regular set of DIBs exists within interval λλ 6770-6865 Å. A possible new sequence of weak DIBs between λλ 5910-5990 Å is presented here. The new sequence is clearly visible in high resolution spectra (R >~ 100,000) of some hot, reddened stars. Wavenumbers' differences, or spacings, between the most strong bands have values ~35, ~40 cm-1, which are very similar to those, found for DIBs near 6800 Å.
