Abstract

We examine Herschel Space Observatory images of one nearby prototypical outer ring galaxy, NGC1291, and show that the ring becomes more prominent at wavelengths longer than 160 μm. The mass of cool dust in the ring dominates the total dust mass of the galaxy, accounting for at least 70% of it. The temperature of the emitting dust in the ring (T = 19.5 ± 0.3K) is cooler than that of the inner galaxy (T = 25.7 ± 0.7K). We discuss several explanations for the difference in dust temperature, including age and density differences in the stellar populations of the ring versus the bulge.
