Title Testing the magnetar model with the first low-B soft gamma repeater

Author Dr Nanda Rea
Description Soft gamma repeaters (SGRs) are part of a rapidly increasing group of x-ray
sources exhibiting sporadic and powerful emission of short bursts and outbursts,
believed to be magnetars, i.e. neutron stars powered by extreme magnetic fields
(Bvirgul10^14-15 Gauss). We have recently discovered an SGR with a low magnetic
field, SGR 0418+57, during outburst and after it emitted bursts similar to those
of magnetars. X-ray observations show that its dipolar magnetic field cannot be
greater than 7.5x10^12 Gauss, well in the range of ordinary radio pulsars. We
ask here for a joint XMM/Chandra monitoring of the first low-B magnetar SGR
0418+57 in order to have a final measure of its period derivative, hence of it
surface dipolar B field.

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.
