Scientific paper

We propose to continue a pilot study by observing three candidate young (< 10 Myr) clusters of massive (>20 Msun) stars for 10 ks apiece with ACIS-I. The ages, initial mass functions, and total masses, will be determined as part of an LTSA-funded project to study the populations of massive stars in 130 clusters with the VLA, HST, SOFIA, Keck, and Gemini. The observations will (1) identify pulsars, magnetars, and HMXBs, so that we can determine the masses of the progenitors of compact objects, (2) reveal X-ray emisison from colliding-wind binaries, so that we can constrain the binary fraction of massive stars, and (3) measure diffuse X-rays from clusters with a variety of ages, so that we can understand how the winds of the massive stars in clusters interact with their surrounding ISM.
