射电星的复极化角：正交跳跃和星际散射
The complex polarization angles of radio pulsars: orthogonal jumps and interstellar scattering
摘要：
尽管在几何旋转矢量模型中解释了观测到的射电望远镜的偏振角摆动取得了一些成功，但观测到了与预期的S形摆动的许多偏差。在本文中，我们提供了一个简单而可靠的解释，这些变化的基础上的组合的旋转矢量模型，内在的正交偏振传播模式内的脉冲星磁层和星际散射的影响。我们使用模拟来探索这种组合可能产生的现象范围，并简要讨论了确定散射参数的可能性，以了解脉冲星的内在偏振。
英文摘要：
Despite some success in explaining the observed polarisation angle swing of radio pulsars within the geometric rotating vector model, many deviations from the expected S-like swing are observed. In this paper we provide a simple and credible explanation of these variations based on a combination of the rotating vector model, intrinsic orthogonally polarized propagation modes within the pulsar magnetosphere and the effects of interstellar scattering. We use simulations to explore the range of phenomena that may arise from this combination, and briefly discuss the possibilities of determining the parameters of scattering in an effort to understand the intrinsic pulsar polarization.
