Abstract
We study high-energy radiation properties of high-field (10(13)-10(14)G) pulsars in the framework of the outer-gap model. In this model, charged particles are accelerated inside the outer gap, which depends on the magnetic inclination angle and magnetic geometry. High-energy photons emitted by these relativistic charged particles produce electrons/positrons through magnetic pair production on their way from the outer gap to the neutron star surface, and these pairs produce nonthermal X-rays by synchrotron radiation. Applying this model to high- field pulsars, the characteristic gamma-ray energies, nonthermal X-ray luminosity, and gamma-ray luminosity are calculated. Furthermore, comparisons of the predicted gamma-ray fluxes for these high-field pulsars with the sensitivities of AGILE and GLAST are given. We discuss the possibility that some high-field pulsars with ages of similar to 10(4.9) to similar to 10(5.5) yr might be detected by AGILE.
