Scientific paper

W5 is the easternmost portion of an enormous complex of HII regions, star clusters and molecular clouds located at 2 kpc in the Perseus arm. Spitzer mid-infrared images of the "Mountains of Creation" (the bright-rimmed cloud AFGL 4029) are a stunning demonstration of sequential star-formation. Class I protostars are tightly clustered in three regions with slightly older T Tauri stars dispersed about the clusters just ahead of the ionization front advancing into and eroding the molecular cloud. The region is a zoo of high- and low-mass young stellar objects, outflows and nebulae. We propose to image the three clusters with ACIS to characterize X-ray emission from the YSOs, particularly the Class III weak-lined T Tauri stars that cannot be identified through near- and mid-infrared searches.
