1989AJ.....97..700G STAR-FORMATION RATES AND [O II] EMISSION IN BLUE GALAXIES J. S. GALLAGHER Lowell Observatory, Mars Hill Road, 1400 West, Flagstaff, Arizona 86001 H. BUSHOUSE NASA-Ames Research Center, MS 245-6, Moffett Field, California 94035 D. A. HUNTER Lowell Observatory, Mars Hill Road, 1400 West, Flagstaff, Arizona 86001 Received 23 August 1988; revised 31 October 1988 ABSTRACT Observations of [0 II] {lambda} 3727 and H{beta} emission-line strengths are presented from large-aperture spectro-photometric observations of nearby (z < 0.1) optically blue galaxies covering a wide range in surface brightness and luminosity. The [0 II] emission-line equivalent widths in these galaxies primarily lie between 30 and 100 A. Emission-line strengths in nearby blue galaxies thus resemble those found in faint galaxies at moderate-to-high redshifts (z < 0.9). The most actively star-forming nearby galaxies are characterized by surface brightness in the [0 II] line of ~10^-15^-10^-14^ ergs s^-1^ cm^-2^ arcsec^-2^ over spatial distances of more than 1 kpc. The fluxes of the [O II] and H{beta} emission lines are well correlated, and thus [O II] luminosities can be used to derive approximate star-formation rates in blue galaxies.
