Title X1658-298: unveiling the emission mechanism(s) of quiescent X-ray transients


DOI https://doi.org/10.5270/esa-sqeooc3
Author Prof Luigi Stella
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 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.
