The dustiness, luminosity, and metallicity of galaxies
Description
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 less than about -1.0 are observed to be essentially dust-free. 18 refs
