| Description | The aim of this proposal is to verify whether the Lambda Orionis Star Forming region (LOSFR), composed by several dark clouds in a 10 deg diameter ring, was created by a SN explosion coming from the central cluster, or by cloud fragmentation. So far, we have carried out a multiwavelength study of the properties of three clusters within the region, Coll69 (in the center) and B30 & B35 (in the rim), finding clear evidences of age spread between them. We propose to image two regions between C69 and B30 to study the radial distribution of young stellar sources from the center to the rim. While a continuous number of sources would be consistent with a supernova explosion, a clear discontinuity would point towards cloud fragmentation as the most probable formation scenario. |

| 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. |
