标题： Highly-Magnetized Pulsars and Integral

摘要： 完全缺乏周期超过几秒的射电脉冲星导致了存在高周期死亡线的普遍观点。 我们最近提出了在周期-周期导数图的上部区域存在另一个射电静默边界，在高磁场（$B\gtrsim 4\times 10^{13}$G）的领域中，没有观测到射电脉冲星。 这个高B边界的原因也是由于磁对产生被抑制，$\gamma\to e^{\pm}$，但主要是因为与奇特的QED过程磁光子分裂，$\gamma\to\gamma\gamma$的竞争，以及基态对产生。 这种机制也可以解释伽马射线脉冲星PSR1509-58的低能谱截止能量，它位于高B死亡线附近。 在本文中，我们总结了这一新“死亡线”的假设，并讨论了一些与对抑制相关的细节，这些细节涉及光子偏振和正电子素形成。 我们确定了几种Integral将作为探测高场脉冲星的有用工具的方式，鉴于射电静默边界对高能波段是透明的。 显示英文摘要

摘要： The complete absence of radio pulsars with periods exceeding a few seconds has lead to the popular notion of the existence of a high period death line. We have recently postulated the existence of another radio quiescence boundary at high magnetic fields ($B\gtrsim 4\times 10^{13}$G) in the upper portion of the period-period derivative diagram, a domain where no radio pulsars are observed. The origin of this high B boundary is also due to the suppression of magnetic pair creation, $\gamma\to e^{\pm}$, but mainly because of competition with the exotic QED process of magnetic photon splitting, $\gamma\to\gamma\gamma$, coupled with ground state pair creation. This mechanism could also explain the low spectral cutoff energy of the gamma-ray pulsar PSR1509-58, which lies near the high B death-line. In this paper, we summarize the hypothesis of this new ``death line,'' and discuss some subtleties of pair suppression that relate to photon polarization and positronium formation. We identify several ways in which Integral will serve as a useful tool in probing high field pulsars, given that the radio quiescence boundary is transparent to the high energy bands.
