论文摘要
讨论了长时间无线电瞬态GLEAM-X J162759.5 $ - $ 523504.3（简称Gleam-X J1627）的性质。我们试图在中子恒星场景中理解其无线电发射和脉动，以替代白色矮人模型。我们认为：（1）从无线电发射的角度来看，GLEAM-X J1627可以是无线电磁盘。 （2）从旋转进化的角度来看，GLEAM-X J1627不太可能是孤立的磁场。 （3）1091S期间不太可能是进攻期。 （4）GLEAM-X J1627可能是由于后备磁盘旋转的无线电大声磁盘向下旋转。 （5）由于存在后备磁盘或扭曲的磁场，脉冲星死亡线被修改。在这两种情况下，都可以获得更高的最大加速电位。这可能解释了为什么GLEAM-X J1627仍然是无线电，并且脉冲时期如此长。 （6）对中子恒星磁场和初始磁盘质量的一般约束进行分析。还讨论了区分不同模型的可能方法。
The nature of the long period radio transient GLEAM-X J162759.5$-$523504.3 (GLEAM-X J1627 for short) is discussed. We try to understand both its radio emission and pulsation in the neutron star scenario, as an alternative to the white dwarf model. We think that: (1) From the radio emission point of view, GLEAM-X J1627 can be a radio-loud magnetar. (2) From the rotational evolution point of view, GLEAM-X J1627 is unlikely to be an isolated magnetar. (3) The 1091s period is unlikely to be the precession period. (4) GLEAM-X J1627 may be a radio-loud magnetar spin-down by a fallback disk. (5) The pulsar death line is modified due to the presence of a fallback disk or a twisted magnetic field. In both cases, a higher maximum acceleration potential can be obtained. This may explain why GLEAM-X J1627 is still radio active with such a long pulsation period. (6) General constraint on the neutron star magnetic field and initial disk mass are given analytically. Possible ways to discriminate between different modelings are also discussed.
