Title Catching a Fading Transient Anomalous X-ray Pulsar in Transition

Description The recently discovered 5.5s pulsar XTE J1810-197 is the first confirmed Transient Anomalous X-ray Pulsar (TAXP), likely a magnetar with a huge magnetic field of 3E14 G. XTE J1810-197 is currently in outburst but fading with a 300 day e-fold time. Archival data spanning 24 yrs indicate that this is a short-lived active state, which implies the existence of a vast population of unexplored young NSs. From its lack of pulsations and softer spectrum in quiescence, XTE J1810-197 may also hold the key to unify the magnetar model for SGRs, AXPs, and central compact objects in SNRs. We propose to continue our semi-annual XMM monitoring campaign of XTE J1810-197 to follow its flux, spin, and spectral evolution, to capture for the first time a complete cycle of a TAXP from quiescence, to outburst, and back.

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.
