Scientific paper

An analysis of IRAS data for a sample of classical (optically selected) Seyfert galaxies is presented. The IRAS fluxes at 25, 60, and 100 μm are found to be uncorrelated or only very weakly correlated with the ultraviolet-optical continuum flux and the fluxes at 3.5 and 10 μm. This provides further evidence that the active nucleus is not the principal source of far-infrared emission. The IRAS measurements for the Seyfert galaxies are compared to IRAS observations of a sample of normal spirals and to a sample of H II region (starburst) galaxies. The distribution of far-IR luminosities and of 60 - 100 μm colors for the Seyfert galaxies and the starburst galaxies are indistinguishable. This indicates that star formation produces the bulk of the far-IR emission in Seyfert galaxies.
