Description | In order to better understand the conditions leading to superflares, which are extremely rare reoccurring from 500-5000 years (Maehara et al., 2012), we must study superflares from large statistical samples of solar-analogs. From recent Kepler studies, superflares are identified in only a few slowly rotating, solar-analogs. No X-ray follow-up exists for these stars. We request XMM-Newton follow-ups of the three identified slowly-rotating, high orbital period superflare Kepler stars. We will compare stellar magnetic activity levels derived from the X-ray observations of these known superflare solar-analog stars with historical magnetic activity in 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. |
