Title Eclipse mapping of 4U 2129+47: unveiling emission mechanisms of quiescent SXRTs


DOI 10.5270/esa-yxhyvqa
Author Dr Luigi Stella
Description In addition to neutron star, NS, cooling, different mechanisms might power the X-ray emission of quiescent soft X-ray transients, SXRTs: a. accretion onto the NS surface or, b. down to the magnetosphere; c. shock emission from the wind of a turned-on radio pulsar. In cases a. and b. the harder X-ray emission originates close to the NS, while in case c. over binary separation scales. A 60 ks XMM observation of the eclipsing SXRT 4U 2129+47 will unambiguously determine the production site of this emission, shedding light on the physics of fast spinning, weakly magnetic neutron stars subject to low mass inflow rates.

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.
