| Description | We propose to obtain XMM-Newton observations of three spectroscopically single superflare stars with large rotation periods (Prot >10 d) to test whether their coronae adhere to the rotation--activity paradigm. While the strongest flares observed on the Sun release about 1e32 erg, Kepler observed a rare species of G-type dwarfs that produce white-light flares releasing up to four orders of magnitude more energy. Notwithstanding their enormous optical outbursts, we identified two single superflare stars, whose coronae seem to adhere to the conventional rotation--activity relation. Combining the available information, we identified the best single superflare stars to enlarge the sample of our X-ray study. |

| 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. |
