Scientific paper

Cep A is a region of intense star formation with a well-studied bi-polar molecular outflow, the nearest identified high-mass protostars, and X-ray Herbig-Haro (HH) objects. Unresolved areas of X-ray emission make it a prime target for Chandra/ACIS-I. We propose an 80 ks observation to measure the spatial structure, spectrum, light curve, and intensity of the X-rays, including HWX, the unresolved X-ray candidate for the power source, and to identify counterparts. The goal is to increase our understanding of the energy sources and the outflows. We will also image a nearby ridge of hard X-ray emission to investigate its origin. We will use Chandra s superior spatial resolution to clarify the puzzling offsets between the X-ray emission and the areas of peak optical excitation in HH 168.
