Abstract:
This paper is the first of a series whose aim is to perform a
systematic study of A-type supergiant atmospheres and winds. Here we
present a spectral atlas of 41 A-supergiants observed by us in high
and medium resolution in the visible and ultraviolet. The atlas
consists of profiles of the Hα, Hβ, Hγ, Hδ,
Hε, Ca II (H and K), Na I (D1 and D2), Mg II4481, Mg II
[uv1] and Fe II [uv1, uv2, uv3, uv62, uv63, uv161] lines for 41 stars
with spectral types ranging from B9 to A9 and luminosity classes Ia,
Iab and Ib, and provides the basic data for a thoughtful study of
these stars. The overall characteristics of the sample as well as the
data reduction procedures are described. We also present some examples
of spectral variability.
