| Abstract | The aim of this proposal is to apply to the X-ray bright intermediate activitystar xi Boo A the classical plasma diagnostics of density, emission measure andabundances, and non-classical optical depth diagnostics available in XMMspectra to: (i) understand both the structure of and relationship between 1 and10 MK plasma in its corona; (ii) determine the nature of its abundance anomaliesas a function of temperature; (iii) examine the stability and time-dependence ofthe hot and cool coronal emission. This will tell us to understand veryactive coronae as they relate to the solar corona; the structure of hot plasmaon active stars relative to cooler plasma; energy balance and heating require-ments on such stars; and the effects of active coronae on stellar evolution. |

| 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. |
