LITTLE THINGS: Star Formation at the Extremes
by Deidre Hunter (Lowell Observatory)
Dwarf galaxies demonstrate star formation at the extremes of
metallicity and gas density, stressing current models of star
formation but giving us an opportunity to examine star formation under metallicities more like those in the early universe. LITTLE THINGS is a multi-wavelength survey of 41 dwarf galaxies,with the centerpiece being deep, high spatial and spectral resolution HI VLA maps. I will discuss what we have learned about star formation in the realm of low metallicity and low gas densities and the problems that remain.
