|Title||LMXB.s in the Galactic Halo: The Nature of UW CrB|
|Author||Dr Pasi Hakala|
|Description||We propose to observe UW CrB (MS1603+26), a 111 min period high galactic latitude interacting binary. This high inclination system provides us with a unique astrophysical laboratory to study the structure and evolution of the precessing warped discs, important in many areas of astrophysics. With its short orbital period and rapid variability in the accretion disc structure (as demonstrated by the rapidly changing optical light curve shapes), UW CrB is probably the best test case for the theories of accretion disc eccentricity, warping and precession. Furthermore, as a probable halo object, the system will also serve as a valuable comparison case for the LMXB evolutionary scenarios.|

|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.
