本文计算了旋转驱动恒星磁层中电磁级联产生的X射线和光学波段同步辐射的最大亮度。我们发现，对于自旋向下光度L sd≤ 10 35 erg s− 1的双光子双星，即使考虑到加速粒子发射的γ射线光子的全部允许能量范围，观测到的非热光度也高于双光子碰撞产生的同步辐射对的最大光度。来自内区的同步辐射可以解释观测到的非热光度，因此Lsd ≤ 10 35 erg s− 1的γ射线双星在磁层中会有多个粒子加速器。
We calculate the maximum luminosity of the synchrotron radiation in X-ray and optical bands, which is originated from the electromagnetic cascade in the magnetosphere of rotation-powered pulsars. We find that for pulsars with spin-down luminosity L sd≤ 10 35 erg s− 1, even if the full allowed energy range of the γ-ray photon emitted by the accelerated particles is taken into account, the observed non-thermal luminosities are higher than the maximum luminosity of synchrotron radiation from pairs created by two-photon collision. The synchrotron radiation from the inner region could explain the observed non-thermal luminosities, so that the γ-ray pulsars with L sd≤ 10 35 erg s− 1 would have multiple particle accelerators in the magnetosphere.
