Are local neutron stars the source of gamma ray bursts? ... Abstract We investigate models for the galactic neutron star origin for gamma ray bursts given the current parameters from the BATSE experiment. ... We also consider two-population models and find that we cannot reproduce any two population model consisting of a combination of halo and local bursts in which the local bursts originate from further than 1 kpc. ...
