Description We propose to obtain XMM-Newton snapshots of seven of the most slowly rotating
G-type superflare stars identified by the Kepler satellite to test whether they
adhere to the rotation-activity paradigm. While the strongest flares observed on
the Sun release about 1e32 erg, Kepler observed G-type dwarfs that produce
white-light flares releasing up to four orders of magnitude more energy.
Curiously, many of these superflare stars are apparently slow rotators.
Notwithstanding, our recent XMM-Newton campaign showed that these stars can be
extremely bright X-ray sources (about 1e30 erg/s). Consequently, we identified
the slowest rotators among the superflare stars amenable to X-ray observations
to study their X-ray emission.

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.
