Recently observers with both XMM and Chandra detected the first X-rays 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 X-raysources 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 X-ray emission, each with 40-ks Epic pn (mediumfilter) observations: HH80/81, HH32, and HH168 (Ceph A West).

Mission Description
The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs second cornerstone of the Horizon 2000 Science Programme. It carries 3 high throughput X-ray telescopes with an unprecedented effective area, and an optical monitor, the first flown on a X-ray observatory. The large collecting area and ability to make long uninterrupted exposures provide highly sensitive observations. Since Earths atmosphere blocks out all X-rays, only a telescope in space can detect and study celestial X-ray sources. The XMM-Newton mission is helping scientists to solve a number of cosmic mysteries, ranging from the enigmatic black holes to the origins of the Universe itself. Observing time on XMM-Newton is being made available to the scientific community, applying for observational periods on a competitive basis.
