Abstract | Modeling the thermal X-ray spectra and pulse profiles of radio millisecondpulsars (MSPs) provides important insight into the properties of neutron stars(NSs). In the nearest MSP, J0437--4715, with such modeling we are able to placeconstraints on the mass-to-radius ratio of the star, the B-field geometry, andsurface properties. Application of this powerful method on another system wouldprovide a crucial validity check and allow an additional set of measuremens. AnXMM-Newton X-ray study of the nearby PSR J0030+0451, may lead to a major advancetowards constraining the NS equation of state and other important NS parameters. |

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. |
