Author Dr Jeremy Drake
Description The aim of this proposal is to apply to the X-ray bright intermediate activity star xi Boo A the classical plasma diagnostics of density, emission measure and abundances, and ..non-classical. optical depth diagnostics available in XMM spectra to: (i) understand both the structure of and relationship between 1 and 10 MK plasma in its corona; (ii) determine the nature of its abundance anomalies as a function of temperature; (iii) examine the stability and time-dependence of the ..hot. and ..cool. coronal emission. This will tell us to understand very active coronae as they relate to the solar corona; the structure of hot plasma on 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 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.
