| Abstract | PSR B1259-63 is a unique binary system with a radio pulsar from which unpulsedX-ray, gamma-ray, and radio emission was observed. The pulsar is in a highlyeccentric 3.4 year orbit around a Be star. Collision of the pulsar wind with thewind of Be star plays a crucial role in generation of the observed emission. Thegoal of this proposal is to investigate, for the first time, simultaneous X-ray(XMM-Newton) and GeV gamma-ray (Fermi) spectral evolution of the system as thepulsar passes through the Be star disk. Details of the X-ray/gamma-ray spectralevolution will allow to probe the physical mechanism(s) of particle accelerationand interactions during collision of relativistic pulsar wind with the wind fromthe massive star. |

| 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. |
