[26.06] Mapping the Star-Formation History of the Small Magellanic Cloud

J. Harris (Space Telescope Science Institute), D. Zaritsky (Steward Observatory)

Based on the UBVI photometry of 6 Million stars in the Small Magellanic Cloud (SMC) from our Magellanic Clouds Photometric Survey, we present independent star-formation histories (SFHs) for 420 SMC subregions, covering the entire central 4x4 degrees of this galaxy. The collection of SFHs allows us to construct a detailed and comprehensive map of the history of star formation in the SMC. This work represents the most complete reconstruction of the SMC's history yet performed. We compare our results to a simple model in which star formation bursts are triggered by past close interactions with the LMC and Milky Way.
