Description | We propose to search for Be + white dwarf binaries in a sample of Be-rich young open clusters totaling over 100 Be stars. XMM has the capability to efficiently detect white dwarfs accreting from the circumstellar envelopes of Be stars. So far no such system has been confirmed and as long as none is found the models on which our understanding of massive X-ray binary evolution are based remain suspect. Making the census of Be + white dwarfs binaries allows to select between the different models put forward to explain the Be phenomenon. This programme is supported by an ongoing optical spectroscopic survey of these clusters conducted by our group. |

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. |
