Description Despite its relatively high abundance amongst early-type stars, only a few B-
stars have ever been observed with gratings. This resulted in our current poor
understanding of the nature of X-ray emissions from these objects. High-
resolution X-ray spectra of O-stars provides us a case where such gratings have
significantly inproved our knowledge of the physical parameters, notably by
revising down the mass-loss rates of those objects. We thus propose to complete
the high-resolution survey of early-type stars by observing the X-ray brightest
B stars, i.e. within reach of XMM RGS. They will help us better characterize and
understand the overall X-ray emission of these hot objects, and its impact on
the B-star winds.

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.
