A high-resolution study of massive YSOs in the Magellanic Clouds

Jacob Ward , ARI

The effects of metallicity on the physical processes that govern the formation of massive stars are undoubtedly significant yet remain poorly understood. At distances of ~50 and ~60 kpc, the sub-solar metallicity Magellanic clouds present a unique opportunity to study star formation on small spatial scales in environments which differ significantly from those of our own Galaxy. Using integral field spectroscopic data obtained with VLT/SINFONI we have investigated the properties of 19 Spitzer selected massive YSOs in the Small Magellanic Cloud and 8 in the Large Magellanic Cloud at sub-parsec resolutions for the first time. A detailed comparison of these objects with a large sample of comparable Galactic sources has revealed significant differences in the properties of YSO in the lower metallicity Magellanic Clouds and hints towards a significant relation between metallicity and accretion rates.
