Abstract

Outer-disk star formation commonly occurs in nearby spiral galaxies (∼30% of cases). However, our understanding of star formation is mostly based on observations of the brighter portions of galaxies and may not be applicable to outer-disks. I use images of young, high-mass, resolved stellar populations from the Hubble Space Telescope to probe outer-disk star formation in two galaxies NGC2915 and M83. Using these data, I develop a novel method to constrain the initial mass function, investigate the local star formation law and star formation thresholds and thus further our understanding of outer-disk star formation.
