     Other missing neutron stars might be the unpredictable soft gamma-ray repeaters (SGRs), the recurrent soft X-ray transients discovered in the 1980s. Although there are only a few examples known at present, SGRs have attracted a lot of attention lately because of their unique characteristics.

     The radio-silent neutron stars include anomalous X-ray pulsars (AXPs), soft gamma-ray repeaters (SGRs), and “quiescent” neutron star candidates in SNRs. There is growing evidence that AXPs and SGRs are indeed magnetars (see [109] for a review).
