摘要:

BATSE measurements suggest1that the distribution of gamma‐ray burst sources is spatially nonuniform, but as yet shows no discernible anisotropy. This is not consistent with the distribution expected solely from a local galactic population of neutron star sources. We suggest, however, that the inconsistency can be reconciled if there are at least two distinct classes of bursts, both of which originate on galactic neutron stars, but which differ by a factor of 104or more, in mean luminosity. We show, as an example, that the observedV/Vmaxdistributions and anisotropy constraints of gamma‐ray bursts are consistent with those expected from a combination of two such classes, resulting from different burst mechanisms on a single galactic, high‐velocity, neutron star population.
