| Description | We will perform EPIC observations of two Galactic globular clusters to detect the cataclysmic variables (and other binaries or their progeny) in these clusters. From the spectra (or X-ray colours) and lightcurves we will determine the nature of the X-ray sources, identify the cataclysmic variable orbital periods and detect white dwarf spin periods in the brightest intermediate polars (magnetic cataclysmic variables), to show why cataclysmic variables show fewer outbursts in globular clusters than in the field. The populations, positions and nature of the objects will also help us understand the formation mechanism of cataclysmic variables in globular clusters and to comprehend their possible contribution in slowing the inevitable core collapse of these very dense stellar systems. |

| 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. |
