Description We request 12 HST orbits of the HMXB M33 X-7, to secure COS spectroscopy. M33 X-7 is a strong source of X-rays which influence the donor star wind and affect its dynamics. Therefore, we request 25 ks of XMM time to obtain X-ray spectroscopy simultaneously with the UV observations, to be performed at three key orbital phases, tracing the BH eclipse, egress, and inferior conjunction. From the eclipse spectrum we will measure the wind velocity and mass-loss rate of the donor star. Realistic wind parameters are needed to develop the models of massive binary evolution towards binary BHs. Coordinated UV and X-ray measurements in eclipse and egress will describe the gas flows towards the BH and establish its accretion efficiency, probing the theories of accretion onto a BH.

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.
