Abstract

We test the empirical relation between ultraviolet color and attenuation as derived for starburst galaxies with a wide assortment of galaxy types detected by the Galaxy Evolution Explorer and find that it systematically overestimates the far-ultraviolet attenuation of our sample by ∼0.5 mag. Our efforts to find an additional parameter that could improve the starburst reddening relation were unsuccessful. In particular, UV - K_s colors (in non-matching apertures) show no correlation with the offset from the starburst reddening relation, suggesting either that UV - K_s colors are a poor tracer of present to past average star formation history (the "b" parameter) or that the intrinsic dust distribution/geometry may be responsible for moving galaxies off the correlation. It is possible to reduce the systematic overestimate of A_FUV by using the linear correlation derived from our sample, which simply lowers the starburst predicted values of A_FUV by 0.58 mag. The scatter, however, remains large at 0.89 mag.
