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。
This paper studies the outer gap model of pulsars,analyzes the differences between traditional outer gap model and the new one,and points out that the electric field created from the pulsar surface is very strong but the electric field along the magnetic field is almost zero,and charged particles are accelerated to relativistic energy in outer gap resulting in high energy radiation.
研究了脉冲星的外间隙模型,分析了传统的外间隙模型和新的外间隙模型之间的不同之处。
