Abstract:
The authors present digital spectra of O to M stars, luminosity
classes V, III, and Ib in the wavelength range 5750-8950Å, at
15.5Å resolution. The stars follow well defined morphological
sequences in both temperature and luminosity. This wavelength region
and resolution, combined with the high sensitivity of silicon-based
detectors, are very useful for spectral classification. Details of
the observations, identifications of the main spectral features, and
spectral lines most sensitive to temperature and luminosity are given
in the paper.
