Title The young open cluster around 25 Orionis

Author Dr Elena Franciosini
Description We propose to observe the young (7-10 Myr) open cluster recently discovered around the B1Vpe star 25 Orionis. We will obtain EPIC imaging and spectra of the cluster, to investigate the X-ray properties of its pre-main sequence population, and to search for new cluster members. The derived properties will be compared with those of the younger sigma Ori and lambda Ori clusters, to investigate the effects of age and of the ambient environment on pre-main sequence coronal activity.

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.
