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