Description | Measuring the spectrum of quiescent neutron stars in globular clusters allows strong constraints on their mass and radius, with implications for the physics of matter at high densities. We identify the quiescent neutron star in M13 as the ideal candidate to study with XMM-Newton, due to its high observed X-ray flux, low N_H, and angular separation from contaminating sources. A 100-ks EPIC exposure will allow us to constrain the fitted neutron star radius within <1 km, for a 1.4 M mass. |

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. |
