Abstract | GT-This proposal has two main objectives: (i) to measure the X-rayluminosity of very low mass stars and brown dwarfs in the Pleiades; (ii)to obtain high quality EPIC X-ray spectra for brighter Pleiades members.The Pleiades is one of the nearest and best-studied open star clusters tothe Sun and, with the Hyades, has formed the basis of many extensivestudies of stellar and galactic structure and evolution. The surfacedensity of stars in the Pleiades makes it an ideal target for XMM. OurXMM field is centred on the brown dwarf Teide 1. |

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. |
