Abstract: Soft gamma-ray repeaters (SGRs) are a rare class of astronomical object that are associated with young neutron stars born in supernova explosions. There is indirect evidence that SGR neutron stars have very strong magnetic fields — hence their designation as so-called ‘magnetars’. New observations of the X-ray flux from one of these objects now provide a stronger case for massive magnetism (1014gauss or more) and that the source of the gamma-ray bursts is sudden fracture of the star's rigid crust.
