论文摘要
据报道，Magnetar SGR 1935+2154具有抗glitch，伴随着快速无线电爆发和瞬时脉冲无线电发射。在风制动模型中，此三重态事件告诉人们（1）SGR 1935+2154没有强烈的颗粒风，可以通过持续状态下的磁性偶极子制动来近似； （2）它的抗glitch是由于增强的颗粒风，类似于磁铁中的第一个抗glitch。 （3）其瞬时脉冲无线电发射可能是由于爆发过程中的发射光束降低所致； （4）增强的颗粒加速电位和脉冲星死亡线可能不是主导因素。
The magnetar SGR 1935+2154 is reported to have an anti-glitch, accompanied by fast radio bursts, and transient pulsed radio emission. In the wind braking model, this triplet event tells people that (1) SGR 1935+2154 does not have a strong particle wind and can be approximated by magnetic dipole braking in the persistent state; (2) Its anti-glitch is due to an enhanced particle wind, similar to the first anti-glitch in magnetars; (3) Its transient pulsed radio emission may be due to a decreasing emission beam during the outburst; (4) The enhanced particle acceleration potential and pulsar death line may not be the dominate factor.
