Search for X-rays from 3 HH Objects

Recently observers with both XMM and Chandra detected the first Xrays fromprotostellar outflows. These are Lynds 1551 IRS5 with XMM (Favata et al. 2001)and HH2 with Chandra (Pravdo et al. 2001). Both objects are dim and soft Xraysources that remained undetectable until the advent of these exceptionalobservatories. HH objects are formed when material outflowing from protostarssmashes into the interstellar medium to form shocks. We propose to survey the 3next most likely HH sources of Xray emission, each with 40ks Epic pn (mediumfilter) observations: HH80/81, HH32, and HH168 (Ceph A West). truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
