We analyse a sample of about 500 MK stan- dards of cool spectral types (G to M) for to compare the visual absolute magnitudes obtained from both Hipparcos data and Schmidt-Kaler calibrations. Our purpose is to va- lidate our spectroscopic work (Gines

On the basis of spectroscopic CCD material obtained at the Haute Provence Observatory, we provide line identifications and equivalent width measurements in the wavelength region 4086-8780 A of the spectrum of MWC 17. Four hundred emission features ar

We provide spectral classifications for a sample of 137 stars mentioned as having composite spectra. The classifications were carried out on 33 A/mm spectra in the region A. Of these 137 objects, 115 correspond in the infrared to cool stars (G, K or

We present and discuss the observations of 14 Ae and A type shell stars in the visual, the Hα region and the near infrared. At least 57% of these stars are spectrum variables. The Paschen lines are formed in a region which has the characterics of gi

We analyze the work of three teams of classi- ers providing spectral classications in the range of late B-type to early F-type stars. With the help of a statistical model we derive an accuracy of 0:7 luminosity classes for the spectroscopic luminosit
