2744 20160706140701.0 ASTROimport-901 Boyer, M. L. 2014 Asymptotic Giant Branch (AGB) stars may be the dominant stellar dust source in galaxies, potentially driving galactic chemical evolution. Specifically, the dustiest ``extreme'' AGB stars, which comprise 5% of the AGB population, provide more than 70% of the AGB-produced dust in the Magellanic Clouds (Riebel et al. 2012; Boyer et al. 2012). Despite their importance, these stars have only been studied in detail in the Magellanic Clouds, which cover a limited range in metallicity. Here, we present the first results of the DUST In Nearby Galaxies with Spitzer (DUSTINGS) post-cryogen Spitzer program. The DUSTINGS program was designed to identify and characterize these extreme AGB stars in a complete infrared census of resolvable Local Group (2 Mpc) dwarf galaxies, which span a wide range of galactic environments. We find hundreds of extreme AGB star candidates and estimate their dust-injection rates.
