| 英文摘要 | In this paper, we study nonthermal high energy radiation from old rotation-powered pulsars with ages greater than 10(6) yr based on the revised outer gap model. In this model, the inclination angle and geometry of the magnetic field have been taken into account, and the fractional size f of the outer gap is determined by the electron/positron pair production process. The cascade process caused by the back-flowing particles moving from the outer gap to the star will produce the observed nonthermal X-ray emission, and the relativistic particles accelerated in the outer gap will produce gamma-rays via curvature radiation. For nine old pulsars which have been detected to have nonthermal X-rays, we first use the observed nonthermal X-ray emission to estimate reasonable inclination angles, and then estimate their gamma-ray emissions. We also study the possibilities of gamma-ray emissions from other old rotation-powered pulsars. We compare our predicted gamma-ray flux with the sensitivities of AGILE and Fermi. |
