Abstract | The program is aimed at obtaining a phase-coherent timing solution for theperiod evolution of XTEJ1810-97 (XTE),continuing the successful X-ray monitoringof this unique Anomalous X-ray Pulsar (AXP).XTE is a transient magnetar, aneutron star (NS) whose quiescent emission is likely due to the decay of anextremely strong magnetic field (10e15 G).Previous analysis suggested a longterm precession (2100 d) of the source spin axis.The pointings we request areaimed at studying the period evolution of XTE and prove the long termprecession.XTE could be a unique precessing NS.The effective presence oflong-term precession could shed light on the physical properties of the NScrust/core, thus, on the physical properties of extremely high density matter |

Mission Description | The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs 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 Earths 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. |
