| Description | Tau Boo is the first star other than the Sun which has been observed to have a global magnetic field with switching polarity. In contrast to the Sun, Tau Boo.s magnetic cycle has a duration of only two years. We propose to monitor the star in four short EPIC exposures of 8virgulks each, backing up these X-ray observations with ongoing measurements of its magnetic field. This will allow us to compare X-ray luminosities and coronal temperatures derived from EPIC spectra to the magnetic field configuration of Tau Boo. |

| 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. |
