Title The eastern edge of the Kappa Ori cluster

Description Thanks to XMM-Newton observations, we have discovered a young stellar cluster centered on Kappa Ori and unrelated to the background Orion A association. Here we want to use the same method to identify the eastern edge of the cluster by means of a 40 ks observation of the V1818 Ori clump of young stellar objects. By measuring fluxes and luminosities of these objects and comparing these to Orion A luminosities we will infer their distances, and determine whether these are: 250 pc as part of Kappa Ori cluster, 400 pc as part of Orion A, or 900 pc like the Mon R2 association, to which the clump is associated in literature. This type of X-ray programs complement GAIA science in regions of dense dust, where GAIA cannot determine distances of embedded objects.

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.
