|Title||'Grand Unification of Neutron Stars: XMM Observations of PSR B1845-19|
|Author||Prof Victoria Kaspi|
|Description||The past decade has revealed huge diversity in neutron star (NS) properties. From rotation-powered pulsars (RPs) to magnetars to the 'isolated neutron stars. (INSs), the leading physical characteristic in defining a NS.s observational behavior has been argued to be magnetic field B. Here we propose X-ray observations of a high-B radio pulsar which represents a key juncture among the above 3 observationally distinct classes. We request XMM re-observations of PSR B1845-19 (original observations were contaminated by background flares), a very nearby high-B RP having spin parameters similar to those of the INSs, to test whether B is the 'grand unification. parameter, as predicted in recent models of NS B decay.|

|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.
