On Line Blanketing in Solar Spectra
Abstract
Summary. We have obtained spectra in the range 7000-11000 A of the nuclei of the Seyfert galaxies NGC1068, NGC3516, NGC4051, NGC4t5t and of the nucleus of NGC 3031 (M 81). The spectra of NGC 1068 and NGC 4151 are caracterized by the high intensity of the lines' [S III] 9069 and 9532 and He 110830, while these lines are absent or weak in the other spectra. An interpretation is given in terms of a higher continuum contribution in these latter spectra, probably due to stellar emission. Key words: spectres infrarouge noyaux de galaxies de Seyfert
