论文摘要
最近，报告了一个快速无线电爆发的16天周期性。我们建议这种16天的周期性可能是由于后备磁盘被迫对中子恒星的强迫进攻。当旋转轴与磁盘平面的正常方向未对准时，中子恒星将预言。中子星的偏心率可能是由于旋转或强磁场等引起的。我们发现可以使用后备磁盘的典型质量来理解16天的周期。有关中子星旋转期的极化观察和信息可能有助于区分不同的模型。可以使用后备磁盘强迫进攻可以一起理解脉冲星，磁铁和快速无线电爆发中可能的进动观测。
Recently, a 16-day periodicity in one fast radio burst is reported. We propose that this 16-day periodicity may be due to forced precession of the neutron star by a fallback disk. When the rotation axis is misaligned with the normal direction of the disk plane, the neutron star will precess. The eccentricity of the neutron star may be due to rotation or strong magnetic field etc. We found that the 16-day period may be understood using typical masses of the fallback disk. Polarization observations and information about the neutron star rotation period may help to discriminate different models. The possible precession observations in pulsars, magnetars, and fast radio bursts may be understood together using forced precession by a fallback disk.
