|Title||Phase Resolved High Resolution Spectroscopy of LMC X-4|
|Author||Dr Konrad Dennerl|
|Description||We propose to utilize the high spectroscopic capabilities of XMM and its impressive photon collection power to study the accreting X-ray binary system LMC X-4. With its rich variety of phenomena, LMC X-4 offers a wealth of information for detailed studies of the accretion process. Phase resolved spectroscopy of emission lines, in particular of the iron line complex, will not only provide information about the ionization stages, but also on Doppler broadening and Doppler shifts. Such studies may be particularly rewarding for LMC X-4, since EXOSAT observations showed evidence for relativistic Doppler splitting of the iron emission line over the 13.5 s pulse period.|

|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.
