|Title||Coronal Activity in the Young Galactic Open Cluster NGC 1039 [M34]|
|Author||Dr David James|
|Description||We propose to survey, in X-rays, the young (250 Myr) open cluster NGC 1039. Its unique astrophysical importance lies in its intermediate age, and the fact that ROSAT X-ray observations already exist of the similarly aged (220 Myr) NGC 6475 cluster. The X-ray characteristics of these middle-aged open clusters can then be compared to ROSAT (and-or XMM-CHANDRA) observations of the young Alpha Persei (50 Myr), Pleiades (100 Myr) and the older Hyades (700 Myr) clusters. Using this suite of data, we will be able to delineate the early-time rotation-age-magnetic activity paradigm, so that we can make inferences and physical models of the physical parameters governing low-mass solar-type star evolution during the early (< 700 Myr) main sequence.|

|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.
