| Description | Only seven isolated radio-quiet neutron stars (XINS) emitting thermal X rays are known, too few to address fundamental questions such as the equation of state of degenerate neutron matter. To expand this sample, we have used the Sloan Digital Sky Survey (SDSS) to examine 10,000 ROSAT error circles and identify a dozen X-ray sources lacking plausible optical counterparts. Short Chandra observations of these XINS candidates are underway to pinpoint the sources. The very small Chandra error circle of one observed candidate remains completely optically blank in SDSS, and this ROSAT/Chandra source is a prime new XINS candidate. We propose a 15 ksec XMM observation to obtain high quality X-ray SED information that will elucidate the nature of this intriguing blank-field X-ray source. |

| 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. |
