| Description | GT- Orion-B has four main centers of star formation with cloud core masses from 260-430 solar masses. In ROSAT observations about 50 X-ray sources within 100 sq.amin have been found in NGC 2024. The X-ray sources appeared to be deeply embedded young stellar objects, possibly T-Tauri stars with kT = 1 keV. Excellent positional correlation was found with infrared K band objects. We want to obtain information on the content of point sources, on source variability, on the mass range, on correlation with IR properties, and on the relation of richness of X-ray clusters with parameters like SFE and core mass. |

| 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. |
