|Title||XMM monitoring of PSR B1259-63 and its Be-star: A unique interacting system|
|Author||Dr Werner Becker|
|Description||The aim of this proposal is to monitor the unique pulsar-Be-star system PSR 1259-63 at different orbital phases, mainly away from periastron where no data were collected so far at energies >2 keV. The binary orbit coverage and the high sensitivity of XMM will allow us to study in details the time and spectral variability of the X-ray emission with an unprecedented sensitivity. For the first time we will be able to discriminate the emission from the pulsar and the PSR-Be-star wind interaction. The high statistics of the collected data will be crucial to test theoretical models and to search for pulsed X-rays. Additional information on the Be-star optical emission will be provided by the OM during the observation.|

|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.
