Description Magnetic activity is ubiquitous among solar-like stars and coronal X-ray emission is perhaps the most powerful diagnostic. Stellar X-ray emission decays during the first Gyr by several orders of magnitude. However, it is currently unknown if and how this decay continues for older stars, because observational constraints are sparse due to the X-ray faintness of these systems. We propose to remedy this situation by obtaining X-ray data of old solar analogs, i.e., stars that have essentially the same stellar properties as the Sun so that we sample only age effects on stellar activity. Our sample of 13 old solar analogs will clarify the X-ray future of the Sun.

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.
