Abstract Zeta Pup is the prototypical star for studies of winds in hot stars. It shows rotationally modulated variations in both the total flux and lin widthspresumably due to inhomogeneities on the stellar surface and in the atmosphericdensities, and intrinsic instabilities in the wind structure. We will observeZeta Pup during the PV program in order to test the RGS capability to resolvevelocity fields and bulk motion.

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.
