论文摘要
众所周知，限制了七十年前由k g budden引入的极化的概念，有能力解释在正常脉冲星中看到的圆极化的幅度，其旋转周期为一秒钟，假设是高度型电子质体质量质量。但是，对毫秒脉冲星相同假设下极化的审查表明，它是不可能的，因为限制极化的区域位于光缸之外。本文使用ION-Proton模型对J2144-3933的一般和专门针对圆极化进行了评估，并对正常脉冲星中的观测值进行了相当详细的理解，包括符号变化作为J0908-4913中看到的频率的变化。但这也无法解释由于这些物体中磁层的颗粒数密度较小和折双发性，因此毫秒脉冲中的圆极化。然而，对极化的综述发现，在离子 - 普罗顿模型中，这种独特的过程可以描述它们的圆极化。有人认为，毫秒脉冲星的某些特征显然与限制极化是一致的。
It is known that the concept of limiting polarization introduced seventy years ago by K G Budden has the capacity to explain the magnitude of circular polarization seen in normal pulsars with rotation periods of the order of one second under the assumption of a high-multiplicity electron-positron plasma. However, a review of limiting polarization under the same assumption in millisecond pulsars indicates that it is inapplicable there because the region of limiting polarization lies far outside the light cylinder. The present paper, using the ion-proton model, evaluates circular polarization both generally and specifically for J2144-3933, and gives a fairly detailed understanding of the observations in normal pulsars including the change of sign as a function of frequency seen in J0908-4913. But it also fails to explain circular polarization in millisecond pulsars owing to the smaller particle number densities and birefringence of the magnetosphere in these objects. However, the review of limiting polarization finds that, within the ion-proton model, this distinct process can describe their circular polarization. It is argued that certain features of millisecond pulsar Stokes profiles are clearly consistent with limiting polarization.
