γ射线脉冲星的代参数及其性质

THE GENERATION ORDER PARAMETER OF γ-RAY PULSARS

本文根据电子光子在中子星表面磁层中的级联过程形成γ辐射的机制，引入了一个描述γ射线脉冲星性质的量──“代参数”。根据这个量，我们可以判断哪些脉冲星可能是γ射线脉冲星。另外，这个量与γ射线脉冲星的一些物理量有密切关系，我们发现γ射线脉冲星的光谱指数及平均能量与“代参数”之间存在着很好的关联。

Based on the concept of generation in electron-photon cascade process in the magnetosphere of the surface on a neutron star,we introduce a new concept of generation order parameter.According to it, we can predict which pulsars may be γ-ray pulsars.In addition, this parameter is closely related with some quantities of γ-ray pulsar.We find that there are good relations between this parameter and the spectral index and the mean energy.
