|Title||Studying Stellar Activity with a XMM-Kepler Joint Project|
|Author||Dr Giuseppina Micela|
|Description||We propose to survey 3 sq. deg. of sky within the Kepler target area with 12 XMM pointing of 80 ksec each. We will take advantage of the unprecedented accuracy, duration and duty cycle of the white-light light-curves (LCs), obtained by Kepler on a large, statistically meaningful stellar sample. These allow us to reliably determine the rotational periods of slow rotators and to obtain simultaneous optical and X-rays observations. The proposed observations will allow us i) to derive the size of active regions in a large sample of stars (hundreds, spanning different activity regimes), ii) to constrain coronal heating mechanisms and iii) to explore the slow rotation regime in low mass stars, using a variety of diagnostics described in the proposal.|

|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.
