1990ApJ...364..444v THE DUSTINESS, LUMINOSITY, AND METALLICITY OF GALAXIES SIDNEY VAN DEN BERGH AND MICHAEL J. PIERCE Dominion Astrophysical Observatory, National Research Council of Canada Received 1990 January 17; accepted 1990 May 18 ABSTRACT B-band CCD images have been obtained of 230 galaxies in and near the Virgo and Ursa Major clusters. A coarse classification of these images shows that the"dustiness" of late-type galaxies correlates strongly with their luminosity. Luminous spirals are seen to be much dustier than late-type systems of lower luminosity. The reason for this correlation is probably that luminous galaxies are more metal- rich than fainter objects. Systems with [Fe/H] <~ -1.0 are observed to be essentially dust-free. Subject headings: galaxies: interstellar matter - galaxies: photometry - galaxies: stellar content - stars: abundances
