Abstract | From archival XMM-Newton data of the isolated neutron star RX J1605.3+3249 wefound a candidate (2.5 sigma) period for the star.s rotation of 6.88 s. Wepropose a 56 ks observation to confirm this. The observation will also allow usto verify the existence of a narrow absorption line at 0.58 keV reported fromthe RGS spectrum (van Kerkwijk et al. 2004). If both, the suggested spin periodand the narrow absorption line can be confirmed, RX J1605.3+3249 becomes apotential candidate among the ROSAT discovered isolated neutron stars withthermal X-ray spectrum to measure independently the mass and radius of the star.This would yield important constraints on the equation of state of matter inneutron 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. |
