T. Schmidtkaler et V. Malyuto, TEMPERATURE AND LUMINOSITY EFFECTS IN PHOTOELECTRIC SPECTRUM SCANNER MEASUREMENTS OF FO-K5 STARS, Astronomy & Astrophysics. Supplement series, 120(3), 1996, pp. 423-427
We study the possibility to classify the stars with the use of the pho
toelectric spectrum scanner designed at Astronomisches Institut at Boc
hum using a spectral resolution of about 10 Angstrom. We analyse tempe
rature and luminosity effects in two spectral indices which were expec
ted to be promising as spectral classification criteria from previous
studies.
