We propose the first detailed X-ray study of the eclipsing M-dwarf binaryGSC1314-0530, consisting of two M dwarfs with masses 0.51 and 0.26 solar masses;its period of 0.192636 days makes GSC1314-0530 the M-dwarf system with theshortest known period, with the larger of the components almost filling itsRoche lobe. We propose a 35 ksec observation with XMM-Newton to carry out thefirst in-depth X-ray study of this system with the aim to characterize theactivity properties of this remarkable system and to study the rotationalmodulation of its X-ray flux.

Mission Description
The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs 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 Earths 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.
