Local Group Dwarf Spheroidal Galaxies as Seen by Spitzer
<p>[Poster abstract]Â To complete Spitzer's legacy in the study of the Local Group, we proposed a Cycle 5 program to observe the neglected dwarf spheroidal galaxies with both IRAC and MIPS. Although less obvious Spitzer targets because of their low current star formation rates, dSphs have a range of star formation histories. They are the only nearby environments where metal-poor, low-mass AGB stars are found and as such have the potential to tell us much about this important and poorly-understood aspect of stellar evolution. Here we present the first results from this program, including images and color-magnitude diagrams.</p>
