Title: Study of the Initial Mass Function in Large Magellanic Cloud Star Forming Regions: N159

Abstract: In the Magellanic Clouds the molecular clouds have different physical properties from those in the Galaxy. The star formation process in this low metallicity environment may also differ. We propose to continue our studies of Magellanic Cloud star formation by performing a deep IR census of young stellar objects in two distinct environments in the Large Cloud: N159, a very young and active star forming region; and N159-S, a dense ^12CO cloud with no optical indication of star formation. These regions are contiguous, and the boundary between them marks the "frontier" of star formation proceeding down the molecular ridge south of the well studied region 30 Doradus. We will explore the first-generation IMF in each locale, and look for distributed vs. clustered star formation. The IR imaging data will be combined with data from ISOCAM and SIMBA to strengthen the physical analysis.
