Description | We propose to take RGS spectra of isolated neutron stars. The grand goal is to determine both gravitational redshift and surface gravity from photospheric absorption lines and therewith constrain the equation of state of matter at supra-nuclear density. The required atmospheric modelling should be easiest for the isolated neutron stars because of their apparently completely thermal spectra. Secondary goals are the determination of the photospheric composition, measurement of possible magnetic fields, and the usual studies of variability, etc. We request time for 1RXS J160518.8+324907, the third-brightest isolated neutron star. This source is relatively hot, and an excellent complement to the two brighter but cooler sources, for which observations are already scheduled. |

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. |
