|Title||PSR J1959+2048: A Black Widow.s IntraBinary Shock|
|Author||Prof Roger Romani|
|Description||We propose a 100ks observation of the original black widow PSR J1959+2048, increasing by >3x the X-ray exposure of its intrabinary shock. Fits to these data determine the binary inclination i (used in measurement of the neutron star mass) and the wind momentum flux and sweep-back (used to measure the companion evaporation rate). The X-ray spectra also probe the nature of the IBS particle acceleration, likely due to reconnection in the striped pulsar wind. These measurements advance our understanding of evolution in such close binaries and can help constrain the properties of high density matter.|

|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.
