| Description | Different mechanisms may power the quiescent emission of soft X--ray transients, impacting on the physics of fast spinning, weakly magnetic neutron stars subject to low mass inflow rates: a) the accretion regime; b) the propeller regime; c) the radio pulsar regime. The emission location and spectrum should be: close to the neutron star and soft in cases a) and b); from an extended shock and power-law like in case c). Additional soft emission may originate from neutron star cooling. We propose an 80 ks observation of the eclipsing system X1658-298, covering 3 orbits. This will yield the source quiescent spectrum and exploit the X-ray eclipses to determine where the emission components originate. Only XMM-Newton has the sensitivity and throughput to carry out this study. |

| 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. |
