| Description | The lambda Ori star forming region (5 Myr, 400 pc) is surrounded by a 5 x 5 deg wide molecular ring probably formed by a supernova explosion. Our previous multi-wavelength studies focused on the most well-known areas within the cloud complex. For a complete picture of star formation, believed to be determined by the supernova blast, the large-scale distribution of the pre-main sequence population in lambda Ori needs to be examined. We suspect a further pre-main sequence cluster to be associated with a concentration of B-type stars near the NE of the molecular ring. A search for X-ray emission is the most efficient way of identifying the low-mass cluster. The properties of its members will then be compared to the other lambda Ori subgroups. |

| 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. |
