论文摘要
FRB 180916.J0158+65在大约16天内反复发射快速无线电爆发。我们建议这样的周期性来自发射极的轨道引起的旋转进动，这可能是中子之星。根据同伴的质量，二进制时期的范围为几百到几秒钟。如此紧密的二进制文件的寿命相对较短，这不太可能来自宽二进制的重力衰减。我们评论与GW190425的关系以及Lisa和Ligo检测的可能性。
FRB 180916.J0158+65 has been found to repeatedly emit fast radio bursts with the period in roughly 16 days. We propose that such periodicity comes from orbit-induced, spin precession of the emitter, which is possibly a neutron star. Depending on the mass of the companion, the binary period ranges from several hundred to thousands of seconds. Such tight binaries have a relatively short lifetime, which does not likely come from the gravitational decay of a wide binary. We comment on the relation to GW190425 and the possibility in LISA and LIGO detections.
