The protostellar content of massive star forming regions

We present preliminary results of an effort to inventory the protostellar content of 20 massive star-forming regions and automate the process for application to a much larger sample. The sample was chosen from a set of massive cores well-studied in molecular lines and dust continuum. We measure photometry at wavelengths ranging from 1.25 to 8.0 [Greek small letter mu]m from 2MASS and GLIMPSE images. Protostars are clearly detected at wavelengths between 1.25 and 4.5 [Greek small letter mu]m. Longward of 4.5 [Greek small letter mu]m diffuse PAH emission becomes problematic. Currently, we are limited by our ability to discriminate against fore/background stars. Initial efforts to automate the photometry look promising, although further analysis is needed.
