Abstract:
Diffuse interstellar bands (DIBs) measured in stellar spectra contain
information on the amount of interstellar (IS) matter that is
distributed along the line-of-sight, and similarly to other absorbing
species may be used to locate IS clouds. Here we present a new
database of 5780.5 and 6283.8Å DIB measurements. Those two DIBs have
the advantage that they are strong and also broad enough to be
detectable in cool-star spectra. We also study their correlation with
the reddening.
Description:
The database is based on high-resolution, high-quality spectra of
early-type nearby stars located in the southern hemisphere at an
average distance of 300pc. Equivalent widths of the two DIBs were
determined by means of a realistic continuum fitting and synthetic
atmospheric transmissions. For all stars that possess a precise
measurement of their color excess, we compare the DIBs and the
extinction.
