论文摘要
据报道，最近发现的Radio Pulsar Gleam-X J162759.5-523504.3，据报道，旋转时期非常长的无线电发光度超过了Pulsar的旋转功率。在这封信中，我们严格地计算出源的无线电发光度，即首先在单独的旋转期间，然后在旋转参数和观察频率上首先在旋转期间首先考虑到脉冲 - 发射锥的开头的依赖性。我们还修改了先前报告的旋转功率的价值。我们的分析基于两个幂律指数以及单个幂律指数的频谱数据的描述。即使将脉冲星的开头视为与常规假设一致的频率独立参数，该参数的周期依赖性也意味着相对较小的开头角度，因此无线电亮度远低于旋转功率。尽管我们在频率依赖性开头的物理上更合理的情况下估计较高的无线电发光性，但最高可能的无线电发光度不超过旋转功率。因此，无法将GLEAM-X J162759.5-523504.3的无线电效率用于磁性假设。
The recently discovered radio pulsar GLEAM-X J162759.5-523504.3 with an extremely long spin period was reported to have a radio luminosity that exceeds by orders of magnitude the spin-down power of the pulsar. In this Letter, we rigorously calculate the radio luminosity of the source taking into account the dependence of the opening angle of the pulsar-emission cone first on the spin period alone and then on both the spin parameters and the observing frequency. We also revise the value of the spin-down power reported previously. Our analysis is based on the description of the spectral data in terms of two power-law indices as well as a single power-law index. Even if the pulsar's opening angle is treated as a frequency-independent parameter in line with the usual assumption, the period dependence of this parameter implies relatively small opening angles and therefore radio luminosities well below the spin-down power. Although we estimate higher radio luminosities in the physically more plausible case of a frequency-dependent opening angle, the spin-down power is again not exceeded by the highest possible radio luminosity. The radio efficiency of GLEAM-X J162759.5-523504.3 can therefore not be used in favour of a magnetar hypothesis.
