Description From archival XMM-Newton data of the isolated neutron star RX J1605.3+3249 we found a candidate (2.5 sigma) period for the star.s rotation of 6.88 s. We propose a 56 ks observation to confirm this. The observation will also allow us to verify the existence of a narrow absorption line at 0.58 keV reported from the RGS spectrum (van Kerkwijk et al. 2004). If both, the suggested spin period and the narrow absorption line can be confirmed, RX J1605.3+3249 becomes a potential candidate among the ROSAT discovered isolated neutron stars with thermal 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 in neutron stars.

Mission Description The European Space Agency's (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESA's 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 Earth's 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.
