Descripción
We present the Northern Massive Dim Stars Survey (NoMaDS), a
high-resolution spectroscopic campaign at the 9.2m Hobby-Eberly
Telescope. The project aims at building the most complete and
homogeneous spectroscopic database of hot, massive Galactic OB stars.
NoMaDS is part of an international collaboration that combines
observations from Chilean, Spanish, and Texan facilities. The
contribution of NoMaDS is to complement the other sister surveys by
providing high signal-to-noise echelle spectra (R=30000) of Galactic OB
stars that are too faint for smaller ground-based telescopes. NoMaDS
will provide a sample of about 200 stars, many of which have never been
observed before at such a high resolution.
Here we present the details of the survey, as well as echelle spectra
obtained with the High Resolution Spectrograph since May 2011. This
includes spectra of standard OB stars, Wolf-Rayet stars, binary systems,
and oblique magnetic rotators. This survey will provide unprecedented
spectroscopic database for a more accurate spectral classification, a
quantitative analysis using atmosphere modeling, the detection and
follow up of the orbits of massive spectroscopic binaries as well as the
study of diffuse interstellar bands.
