Blue low surface-brightness galaxies. I. Surface photometry.

ROENNBACK J. and BERGVALL N.

Abstract (from CDS):

As a part of an effort to find young galaxies and unevolved disk galaxies in the nearby universe, we have undertaken a photometric study of 29 blue low surface-brightness galaxies. The objects were selected from the ESO-Uppsala Surface Photometry Catalogue on basis of photometric criteria characterizing metal-poor and/or young galaxies with a homogeneous stellar content. Here we present BVi surface photometry and discuss the results in relation to properties of normal galaxies. The sample is dominated by late type disks (70%) and irregulars with exponential luminosity profiles. The dust content appears to be low. The mean blue disk central surface-brightness of the sample is 23.5±0.2mag/arcsec+2, being fainter 1.9±0.3mag/arcsec2+ than the canonical value for normal disk galaxies. The mean B-V is 0.39±0.02mag. This is ∼0.15mag bluer than normally found for galaxies of comparable morphology.
