| 英文摘要 | We studied the evolution of the X-ray and gamma-ray spectra of the Crab pulsar utilizing the 11-year observations from the Rossi X-ray Timing Explorer (RXTE) and 9-year observations from the Fermi Gamma-ray Space Telescope (FGST). By fitting the spectrum of each observation, we obtained the corresponding flux and then analyzed the long-term evolution of the X-ray (or gamma-ray) luminosities as well as their correlations with the spin-down power of the pulsar. The X-ray flux in 5-60 keV obtained by the Proportional Counter Array of RXTE decreases with a rate of (-2.4 +/- 0.4) x 10(-14) erg cm(-2) s(-1) per day. The X-ray flux in 15-250 keV obtained by the High Energy X-ray Timing Experiment of RXTE and the gamma-ray flux in 0.1-300 GeV by the Large Area Telescope onboard FGST show similar decreasing trends but are insignificant statistically. The 5-60 keV X-ray luminosity L-X is correlated with the spin-down power L-sd by L-X proportional to L-sd(1.6 +/- 0.3), which is similar to the statistical results for young pulsars. |
