Abstract: The Small Magellanic Cloud (SMC) has been imaged from 3.6 to 160μm as part of the Spitzer Legacy program entitled: “Surveying the Agents of Galaxy Evolution in the SMC” (SAGE–SMC). These wavelengths are ideal for studying circumstellar dust, and the full spatial coverage of the SMC (including the bar, wing, and tail) allows for a statistically complete study of its entire dust-producing Asymptotic Giant Branch (AGB) star population. Here, we discuss the infrared colors and spectral energy distributions of the SMC AGB stars, particularly with respect to dust production and mass loss. We also compare the SMC AGB population to those in the higher-metallicity LMC.
