Abstract | We propose to observe the quasi-persistent neutron-star low-mass X-ray binariesKS 1731-260 and MXB 1659-29 once in their quiescent state during Cycle 3 ofXMM-Newton. These observations will strongly constrain the time evolutionbehaviour of the quiescent properties of those systems. In the context of thecooling neutron star model for the quiescent emission in neutron star X-raytransients, our proposed observations will follow the cooling time of the crustand core of the neutron stars in those systems. Our previous XMM-Newton andChandra observations of both systems have already shown that the crusts of theneutron stars in both systems cooled down rapidly, setting stringent constraintson the structure of the neutron stars. |

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. |
