|Title||Coronal thermal structure and abundances of super-metal-rich late-type stars|
|Author||Dr Antonio Maggio|
|Description||We propose to observe the coronal emission from two super-metal-rich (SMR) late-type stars, in order to determine the plasma emission measure distribution vs. temperature, and individual element abundances, from the analysis of EPIC and RGS spectra. These observations, will help to test current hypotheses about the link between photospheric and coronal abundances, and the possible relationship between activity level and metal depletion in stellar coronae. The characteristics of the coronal structures will be also studied by means of direct plasma density estimates from He-like triplets.|

|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.
