| Abstract | From archival XMM-Newton data of the isolated neutron star RX J1605.3+3249 wefound a candidate period for the stars rotation of 6.88 s. We propose three 20ksec observations to confirm this. The observations will also allow to verifythe existence of a narrow absorption line at 0.58 keV in the RGS spectrumreported by van Kerkwijk et al. (2004). If both, the suggested spin period andthe narrow absorption line can be confirmed, RX J1605.3+3249 becomes the bestpotential candidate among the ROSAT discovered isolated neutron stars withthermal X-ray spectrum to measure both its mass and radius. This would yieldimportant constraints on the equation of state of matter in 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. |
