Scientific paper

The L1630 dark cloud contains three very rare Class 0 and at least six Class I protostars. Several of them are tightly clustered around HH 24-26, a site of molecular jets and a luminous but unresolved ASCA X-ray source. We propose to image this region for 70 ks with the ACIS-S in order to (a) search for the onset of X-ray emission in the Class 0 stars, (b) perform precise astrometry of the X-ray emission of the Class I stars, and (c) from spectrometry of the Class I sources, derive spectral parameters of their associated X-ray sources. Our goal is to establish an evolutionary progression in X-ray properties within a single cloud and thus explore the relationship between protostellar X rays, accretion disks, magnetically collimated jets, and large-scale molecular outflows.
