Abstract We propose XMM observations of 4U1700-37, the compact companion to the extremeOf supergiant HD153919, at four different orbital phases. The uniquecapabilities of XMM would allow us to: (i) search for the origin of theobserved, but unexpected, soft component in the X-ray spectrum; (ii) identifythe input spectrum of the Raman-scattered emission lines; (iii) study the natureof the compact X-ray source; (iv) look for the expected, but so far undetectedX-ray pulsations; (v) investigate the accretion flow and detailed X-ray flaringbehaviour. This high-mass X-ray binary is unique in its class and provides theopportunity to address many unsolved issues that can only be studied in thesetype of systems.

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.
