Title: Low surface brightness spiral galaxies. I. Neutral hydrogen content and location in the infrared Fisher-Tully diagram

Abstract

A neutral hydrogen survey has been carried out for a class of spiral galaxies characterized by low surface brightness disks; on average, these systems (denoted LSBs) have projected central surface brightness values smaller by a factor of 3 than the value typical of normal spiral galaxies. The hydrogen mass to blue luminosity ratio M/sub H//L/sub B/ is observed to range from 0.29 to 2.30; the average for 33 systems is 0.87 +- 0.11 (m.e.) or more than twice the value typical for normal late-type spiral galaxies. Infrared aperture photometry, combined with 21 cm line widths, permit the low surface brightness spirals to be located with respect to the H magnitude, ..delta nu.. Fisher-Tully relationship discussed recently by Aaronson, Huchra, and Mould, the LSBs fall below the observed relationship by 0.64 mag. A careful discussion of the factors affecting their location in the H, ..delta..v plane suggests that LSBs have mass-to-light ratios a factor of 1.8 times that typical of normal spirals.
