Using Herschel to Determine the Role of Triggering Processes in forming the Galactic IMF

Toby Moore, James Urquhart, Charles Figura

 

Initial results from the Herschel Hi-Gal survey reveal new populations of embedded young protostars at the edges of Galactic ‘bubbles’. These bubbles have been identified as regions of triggered star formation through analysis of recently observed large-scale CO maps. We determine the star formation efficiency in several of these bubbles and trace the effects of triggering processes in and around them. Through mapping the star formation efficiency in these regions and preliminary determinations of protostellar properties we are able to trace the effects of triggering upon their mass, luminosity and temperature. The effects of star formation efficiency upon the clump mass function are investigated and allow us to predict the contribution of triggered processes to the Galactic IMF.
