Star Formation Histories of Dwarf Satellite Galaxies: Models and Observations
Oleg Gnedin (Univ. Michigan)

I will present new star formation histories of most Local Group dwarfs, derived from the resolved stellar populations observed with HST. The data have an unprecedented quality and time resolution and show a great variety of star formation histories - some continuous, some bursty, some truncated. I will describe the latest models of star formation in small dark matter halos, which address the "missing satellites problem" and help explain the detailed star formation histories of dwarf galaxies.
