Abstract:
Stellar spectroscopic surveys may bring useful statistical information
on the links between diffuse interstellar bands (DIBs) and the
interstellar environment. DIB databases can also be used as a
complementary tool for locating interstellar (IS) clouds. Our goal is
to develop fully automated methods of DIB measurements to be applied
to extensive data from stellar surveys. We present a method that is
appropriate for early-type nearby stars, along with its application to
high-resolution spectra of ∼130 targets recorded with the ESO FEROS
spectrograph and comparisons with other determinations. Using a DIB
average profile deduced from the most reddened stars, we performed an
automated fitting of a combination of a smooth stellar continuum, the
DIB profile, and, when necessary, a synthetic telluric transmission.
Description:
We use high-resolution (R≈48000), high signal-to-noise (S/N≥100)
spectra of nearby, early-type (B to A5), fast-rotating stars that are
mostly located within 400pc. Observations were done with the FEROS
spectrograph at the ESO/Max Planck 2.2m telescope in La Silla and were
part of the LP179.C-0197 program.
