Gamma-Ray Pulsars in Gould Belt and Unidentified Gamma-Ray Sources in Medium Latitudes

Abstract

We study the gamma-ray emission properties of pulsars by using a self-consistent outergap model. The outer gap of pulsars with large inclination anglecan exist even their age >10 6 yr old. We use Monte Carlotechniques to simulate the statistical properties of rotation-poweredpulsars in the Gould Belt. If the pulsar birth rate in Gould Belt is3�10 -5 yr -1, the gamma-ray pulsars in this region, which can be detected byEGRET, will must be dominated by those pulsars with large angles. Wepredict that these gamma-ray pulsars should have a wider period P ~(0.5-0.8)s and with a typical age of several million years old.
