| 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. |
