Description We propose XMM-Newton observations from eclipse ingress to out of eclipse of the high-mass X-ray binary LMC X-4, which represents one of the most extreme cases of mass-transfer in such systems. With the high sensitivity of the XMM-RGS gratings in the range 0.35-2.5 keV, we will be able to detect and identify all the fluorescent emission and discrete recombination lines at low energies. This will allow us to constrain the geometry and temperature of the ionisation zone. Furthermore, in combination with the large effective area of the XMM-EPIC cameras we will be able to address the question whether the poorly studied soft excess is of thermal origin or if it consists of blending of several lines.

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.
