Description Solar twins are stars that closely resemble the Sun. They are an important cornerstone for studies of the Sun as a star and critical for putting the Sun - and our solar system - into context. However, the X-ray properties of solar twins are largely unknown so that the Sun is, rightly or not, often used as representative of its siblings. Here, we propose to remedy this situation by observing a small sample of six nearby solar twins. This will allow us to decide if the Sun.s X-ray properties are indeed representative.

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.
