| Description | This program is aimed at obtaining a phase-coherent timing solution for the period evolution of XTEJ1810-197 (XTEJ), and at continuing the successful XMM monitoring of this unique Anomalous X-ray Pulsar (AXP). AXPs are Magnetars, isolated neutron star (NS) whose emission is due to the decay of a superstrong magnetic field, 10e+(14-15) G. The requested pointings are aimed at studying the period evolution of XTEJ with the goal of demonstrating the presence of a long term (5yr) precession of its rotation axis. XTEJ could be a unique precessing Magnetar (only 3 candidate precessing NSs are known). This would shed light on the physical properties of the NS crust/core core and on the physical properties of matter at extremely high density. We request two pointings to complete the monitoring campaign. |

| 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. |
