摘要:

目前,还没有关于射电天体磁轴和自转轴之间倾角$χ$演化的直接信息。至于脉冲星演化的理论模型,它们既预测了排列,即倾角$χ$向$0^{\circ}$的演化,也预测了它的逆排列,即向$90^{\circ}$的演化。在本文中,我们证明了脉冲间的统计可以给我们的关键测试,以解决对齐/反对齐问题的正交脉冲间的脉冲($χ\approx 90^{\circ}$)的数量急剧依赖于进化轨迹。

英文摘要:

At present, there is no direct information about the evolution of inclination angle $χ$ between magnetic and rotational axes in radio pulsars. As to theoretical models of pulsar evolution, they predict both the alignment, i.e. evolution of inclination angle $χ$ to $0^{\circ}$, and its counter-alignment, i.e. evolution to $90^{\circ}$. In this paper, we demonstrate that the statistics of interpulse pulsars can give us the key test to solve the alignment/counter-alignment problem as the number of orthogonal interpulse pulsars ($χ\approx 90^{\circ}$) drastically depends on the evolutionary trajectory.
