| Gamma-ray emission from neutron stars is considered in two contexts. A new model for gamma-radiation from pulsars is presented which uses the Deutsch fields to model the electromagnetic fields around the star; the structure of and charge motion in these fields is discussed in detail. A widely applicable approximation to charged particle motion in powerful electromagnetic fields is developed and exploited in the numerical simulation of particle motion in our model.; An exploration of the distribution of gamma-ray bursts is also presented, assuming that these objects are the result of interactions between neutron stars located in an extended Galactic halo and stray comets ejected from stellar systems in globular clusters and disk stars. |
