| Description | A handful of Class I protostars have been detected in X rays, but no firmly established Class 0 object has ever been detected as an X ray source. I am proposing to obtain 30 ks pointings with XMM of two small dark cloud regions, each of which is known to harbor high-velocity molecular outflows, long chains of HH emission knots, and low-luminosity Class 0 IRAS sources. The goal of the observations is to determine whether the X ray and other physical properties of these objects and their surrounding environments are different from those of embedded protostars that form in much more massive clouds. Because of their lower density and mass, these small clouds may be more transparent to X-rays and hence more easily probed than a dense cloud like Orion. |

| Mission Description | The European Space Agency's (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESA's 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 Earth's 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. |
