|Title||Monitoring the 2007 periastron passage of the pulsar-binary system PSR B1259-63|

|Description||Non-accreting binary systems containing a spin-powered pulsar and a Be-star provide us with unique opportunities to investigate the interaction between the pulsar and the stellar wind. We propose to monitor the binary system PSR B1259-63 with its companion Be-star SS 2883 during its periastron passage in summer 2007. This XMM-Newton data will enable us to examine the shocked emission in a window around periastron in detail and to monitor how the spectral behavior and the flux evolves when PSR B1259-63 passes through periastron. This observations, which require only a modest amount of observing time, together with archival data taken by ASCA and XMM at other orbital angles will finally constrain the geometry of the Be-star disk.|

|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.
