Abstract | We propose observations with XMM-EPIC/MOS in five distinct sibling associationsbelonging to the Lambda Orionis Star Forming Region (2--5 Myr, 340 pc). We havealready optical, near-IR, and Spitzer photometry, and spectroscopy for objectsdown to 0.015 M(sun). The goals are: i) Assess the membership of our candidatesand detect new members. ii) Derive accurate IMFs for each association, checkingthe universality of the IMF. iii) Study the properties and evolution of theX-ray Luminosity Functions. |

Mission Description | The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs 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 Earths 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. |
