Scientific paper

We propose to observe with CHANDRA ACIS-S the youngest sites of high mass star formation. Recent ASCA observations suggest, that the earliest evolutionary states of massive star formation are associated with hard X-ray emission. A systematic proof of this finding can only come from the superior resolution achievable with CHANDRA. The observations will allow us to resolve the protostellar cluster and, supplemented with high resolution IR and radio data, to identify the nature of the detected objects. The X-ray spectral information will give us important clues on the X-ray production mechanism in high mass protostars, which is up to now unexplored. The observations will also permit to evaluate the impact of X-rays on star formation and chemistry within dense molecular cores.
