In the frame of the revised outer gap model,study the non-thermal X-ray radiation of seven old pulsars observed by Chandra, the predicted values are consistent with the observed date, and calculate the non-thermal X-ray luminosity of old pulsars with outer gaps, and compute the gamma-ray luminosity and gamma-ray fluxes of these old pulsars with outer gaps.
利用新的外间隙模型,研究计算了老年脉冲星的非热X-射线光度,并与Chandra观测到的七颗老年脉冲星的非热X-射线光度的观测结果进行了比较,模型的计算结果和观测数据吻合较好,同时计算了老年脉冲星可能的伽玛射线光度和流量。
