| Description | We have recently discovered the first SGR with a low magnetic field (Rea et al. 2010, Science, 330, 944), SGR 0418+5729, discovered in outburst after it emitted bursts similar to those of magnetars (B<7.5x10^{12} G). This discovery had large implications not only for the magnetar model, but for the pulsars population in general. We have now a tentative measure (at 2.8sigma level) of its period derivative resulting in a B-field =7.1x10^{12} G). We ask now for a final 75ks XMM observation to confirm this detection at >5sigma. This will lead to have a final measure of SGR 0418+5729 dipolar magnetic field, crucial for tuning the magnetar model as well as predict how many "hidden" magnetars there might be within the pulsar population. |

| 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. |
