|Title||The timing properties of the transient magnetar XTE J1810-197 during quiescence|
|Author||Dr Fabio Pintore|
|Description||This program is aimed at obtaining a phase-coherent timing solution for the period evolution of the transient magnetar XTE J1810-187 during its quiescent state. We aim at study the spin evolution during quiescence of the source XTE J1810-197, which is the prototype of the transient magnetars, by means of a phase-connected timing analysis based on joint XMM-Newton+Chandra observations. After a long outburst, XTE J1810-197 returned to a quiescent state where the pulsation is still detectable, unlike other transient magnetars which are not detected during quiescence. In particular, here we request 8 XMM-newton observation with 10ks exposure and one Chandra observation with 20ks exposure, that will give us information on the source spin-down evolution and on its spectral properties during quiescence.|

|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.
