We assume that the soft gamma-ray repeater GB 790107 comes from a weakly magnetized ( B ∼ 10 8 G) neutron star, where shower-type accretion of cometary material results in an optically thick region on the surface of the star. The temperature distri

When radiation loss is considered, we believe that synchrotron radiation of particles beamed along magnetic field generated by such acceleration mechanism as field reconnection is the main mechanism for producing gamma-ray bursts. On the basis of thi

A model of the old and hot neutron stars (age , temperature ) with the low magnetic field as the sources of Gamma-ray bursts is presented. In the range of medium energy , the main radiation mechanism is still the thermal synchrotron radiation. The ab
