Abstract:
We have selected spectra of 232 stars from the IUE archives for
inclusion in an atlas intended for various uses but tailored
especially for the study of stellar winds. The atlas covers the range
in spectral types from O3 to F8. The full atlas covers the reduced
and normalized high resolution spectra from the IUE
long- and short-wavelength spectrographs.
Here we discuss the selection of the stars and the data reduction,
and we present in velocity units the profiles of lines formed in the
stellar winds. The selected lines cover a wide range of ionizations,
allowing a comparison of the profiles from different ions in the wind
of each star and a comparison of the different wind lines as a
function of spectral type and luminosity. We also present the basic
data on the program stars to facilitate study of the dependence of
wind features on stellar parameters such as luminosity, temperature,
escape velocity, and v sin i. We provide an overview of the
characteristic behavior of the wind lines in the H-R diagram.
The complete spectra are available in digital form through the NASA
Astrophysics Data System (ADS). We offer a description of the
electronic database that is available through the ADS and guidelines
for obtaining access to that database.
Description:
In addition to the tabular data described below, spectra for the 232
stars in this atlas are included from Figure 2 of the printed paper,
as well as the 16 H-R diagrams from Figure 3. The spectra are
contained in Postscript files named 'star_nnn.ps', where 'nnn'
represents a number from '001' to '232', inclusive. The H-R diagrams
are contained in Postscript files named 'hrnnnn.ps', where 'nnnn'
represents a number corresponding to the wavelength of the ion in
question, e.g. 'hr1640.ps' is the H-R diagram for He II at 1640
Angstroms. The H-R diagram for all atlas stars (Figure 1 in the
printed paper) is given in file 'hrall.ps'.
