| Description | We propose to observe the complete sample of confirmed binary Be stars with sdO companions. We aim to probe the essentials of binary evolution theory which predicts that Be-type stars are the products of close binary evolution, and that a significant fraction of them have hot companions which were stripped of hydrogen during a mass exchange event. The proposed survey will lead to a characterization of X-ray emission from Be+sdO binaries and establishing their X-ray properties. Furthermore, we propose to measure the X-ray spectra of two prototypical Be+sdO systems, phi Per and o Pup, to measure the hot plasma temperatures and emission measure, and to validate a hypothesis about stellar wind collisions in Be binaries. |

| 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. |
