Scientific paper

We propose to carry out IRAC subarray imaging of bright embedded stars in three of the high mass star forming regions previously imaged with IRAC: S255, NGC7538 and AFGL4029. All three regions contain deeply embedded high mass protostars in high extinction molecular clouds. These subarray mode observations will enable us to obtain unsaturated measurements of the massive protostars and to probe these high extinction regions for deeply embedded associated stars. From this measurement, we can estimate the stellar densities in the immediate vicinities of forming high mass stars and test theories which explain the formation of high mass stars through collisions of lower mass stars.
