论文摘要
Chime/FRB的合作最近报道了在FRB 180916的无线电爆发时间中发现了16天的周期性。J0158+65。我们研究了观察到的周期性是由磁化中子恒星的游离进动引起的,并在恒星磁场的不同组件上放大了约束。使用一个简单的几何模型,其中无线电爆发是从旋转中子星形磁层发出的,我们表明发射模式随时间的函数可以匹配FRB 180916.J0158+65。
The CHIME/FRB collaboration recently reported the detection of a 16 day periodicity in the arrival times of radio bursts from FRB 180916.J0158+65. We study the possibility that the observed periodicity arises from free precession of a magnetized neutron star, and put constraints on different components of the star's magnetic fields. Using a simple geometric model, where radio bursts are emitted from a rotating neutron star magnetosphere, we show that the emission pattern as a function of time can match that observed from FRB 180916.J0158+65.
