| Description | We propose for 68 ksec of observing time on XMM-Newton to monitor X-ray activity on four pairs of virtually identical twin M dwarfs. These twin wide binaries are comprised of stars with nearly identical masses, ages, and compositions. Evolutionary models and conventional thinking suggest that such sets of twin stars should evolve nearly co-equally, resulting in similar levels of magnetic activity. These XMM-Newton data will be used in concert with optical monitoring that provides information about short-term flaring, medium-term rotation periods, and long-term stellar spot cycles, which can then be correlated with X-ray activity. This work is carried out as part of CoI Couperus. Ph.D. thesis. This will be a robust test of magnetic predictability. |

| 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. |
