2010AJ....140.1975S The Larson-Tinsley Effect in the Ultraviolet: Interacting Versus "Normal" Spiral Galaxies Smith, Beverly J.; Struck, Curtis Abstract. We compare the UV-optical colors of a well-defined set of optically selected pre-merger interacting galaxy pairs with those of normal spirals. The shorter wavelength colors show a larger dispersion for the interacting galaxies than for the spirals. This result can best be explained by higher star formation rates on average in the interacting galaxies, combined with higher extinctions on average. This is consistent with earlier studies which found that the star formation in interacting galaxies tends to be more centrally concentrated than in normal spirals, perhaps due to gas being driven into the center by the interaction. As noted in earlier studies, there is a large variation from galaxy to galaxy in the implied star formation rates of the interacting galaxies, with some galaxies having enhanced rates but others being fairly quiescent. Key words: galaxies: interactions, galaxies: starburst, ultraviolet: galaxies =========================================================================== 2011AJ....142...96S ERRATUM: "The Larson-Tinsley Effect in the UV: Interacting Versus "Normal" Spiral Galaxies" (2010, AJ, 140, 1975) Smith, Beverly J.; Struck, Curtis Abstract. Some of the figures in the published article (Figures 7-11 and 18-22) included data points for only a subset of the full sample of galaxies. Here, {see figures}, we provide new versions of these figures, containing data points for the full sample of galaxies. This correction does not affect the conclusions of the paper or the statistics quoted in the paper. ===========================================================================
