Abstract | 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 NSs observationalbehavior has been argued to be magnetic field B. Here we propose X-rayobservations of a high-B radio pulsar which represents a key juncture among theabove 3 observationally distinct classes. We request XMM re-observations of PSRB1845-19 (original observations were contaminated by background flares), a verynearby high-B RP having spin parameters similar to those of the INSs, to testwhether B is the grand unification parameter, as predicted in recent models ofNS B decay. |

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. |
