论文摘要
尽管无线电脉冲星的极化特性具有丰富的现象学，但创建的旋转矢量模型（RVM）仍然是确定脉冲星的束几何形状的最佳方法。我们将RVM应用于Meerkat望远镜观察到的854个无线电脉冲星的样本，以得出有关整个脉冲星人群的结论。主要结果是（i）（i）位置角遍历的几何解释在大多数人群中都是有效的，（ii）RVM倾向于与线性极化相比，RVM倾向于不倾向于通过地几何和相关性的脉冲高度相比，圆形极化的高度相比，循环极化的高度差不多，比较差不多的脉冲高度〜 （iv）在大约三分之一的人群中，在位置角度遍历的正交模式跳跃。所有这些结果都微弱地取决于脉冲星旋转能量。
In spite of the rich phenomenology of the polarization properties of radio pulsars, the rotating vector model (RVM) created 50 years ago remains the best method to determine the beam geometry of a pulsar. We apply the RVM to a sample of 854 radio pulsars observed with the MeerKAT telescope in order to draw conclusions about the population of pulsars as a whole. The main results are that (i) the geometrical interpretation of the position angle traverse is valid in the majority of the population, (ii) the pulsars for which the RVM fails tend to have a high fraction of circular polarization compared to linear polarization, (iii) emission heights obtained through both geometrical and relativistic methods show that the majority of pulsars must have emission heights less than 1000~km independent of spin period, (iv) orthogonal mode jumps are seen in the position angle traverse in about one third of the population. All these results are weakly dependent on the pulsar spin-down energy.
