摘要

来自FAST和MeerKAT调查的数据显著增加了射电脉冲星的数量，这些脉冲星的平均剖面的极化特征已经被详细确定。这使我们证实了早先关于脉冲星磁层中两个正交模式的传播性质和中子星极区粒子产生机制及其演化特征的结论。我们现在可以更有把握地说，由o型模态形成的平均谱线比由x型模态形成的平均谱线宽得多。此外，观测结果证实了粒子生成的经典Ruderman-Sutherland真空模型的有效性，以及磁轴倾角向\(90^{\circ}\)方向旋转角度的演化。

Data From FAST and MeerKAT Surveys As a Test of Radio Pulsar Physics

The data from the FAST and MeerKAT surveys has significantly increased the number of radio pulsars for which the polarization characteristics of their mean profiles have been determined in detail. This has allowed us to confirm earlier conclusions both about the nature of propagation of two orthogonal modes in the pulsar magnetospheres and about the mechanism of particle production in neutron star polar regions and their evolutionary features. We can now say with even greater confidence that mean profiles formed by the O-mode are significantly wider than those formed by the X-mode. Moreover, the observations confirm the validity of the classical Ruderman-Sutherland vacuum model of particle generation, as well as the evolution of the inclination angles of the magnetic axis to the rotation one in the direction of \(90^{\circ}\).
