Abstract | We propose observing solar-mass stars having X-ray luminosities similar to the Suns so as to determine the thermal structure andelemental abundances Z characteristic of such low-activity coronae,observations of which are very underrepresented in the XMM GTOProgram. We have selected 3 stars of different surface gravities(Tau Cet, Beta Hyi and Beta Gem) so that we can compare the coronalproperties as a function of g. We will utilise the H- and He-likelines of abundant elements such as O, Ne, Mg, and Si, as well as theFe L complex lines between 0.7 and 1.5 keV, and the continuumemission in other spectral regions to derive T and Z. |

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. |
