| Description | We propose for XMM-Newton observations of very low-mass objects in the young stellar association around the multiple star sigma Orionis. Our scientific goal is to study magnetic activity of young objects from the hydrogen burning mass limit down to the deuterium burning limit. The sig Ori association contains a number of objects with planetary masses and Brown Dwarfs (BDs); some of the latter ones were shown to be X-ray sources in ROSAT pointings. We plan a multiwavelength study including X-ray and optical observations as magnetic activity is manifested in a large range of the spectrum. These observations could lead to the first X-ray detection of objects close to the planetary mass limit and help to discriminate between BDs and planets in this region. |

| 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. |
