Abstract
We study the possibility of high-energy gamma-ray emission from theknown 1130 radio pulsars based on the outer gap model of high-energy emission from pulsars. We estimate the fractional size of outer gap, theintegrated flux, the gamma-ray luminosity for each known radio pulsar,and find that only 14% of the known radio pulsars are gamma-rayemitters according to the outer gap model. In the sample of possible 156gamma-ray pulsars, our statistical analysis indicates that thedistributions of the spin-down powers and the ages of these pulsarsconcentrate mainly on 1033.5-1039 erg/s and103-107 y, respectively. The predictions of gamma-raypulsars detected by the AGILE and GLAST missions are given.
