| 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. |
