Spectral classifications in the near infrared of stars with composite spectra. III. Study of a sample of 137 objects with the Aurelie spectrograph.


Abstract (from CDS):

We provide spectral classifications for a sample of 137 stars mentioned as having composite spectra. The classifications were carried out on 33Å/mm spectra in the region 8370-8870Å. Of these 137 objects, 115 correspond in the infrared to cool stars (G, K or M) of luminosity classes III, II and I; for 22 stars, we find only hot spectra of types B, A, F or Am, so that they do not fulfil our definition of composite spectra. We detect four new Am stars, and one Am star (HD 70826) turns out to be a composite spectrum object. As in Paper II, the cool components of composite spectra show a strong concentration in the vicinity of G8III.
