高磁场旋转供电脉冲星

High Magnetic Field Rotation-powered Pulsars

摘要:

异常X射线暴和软伽马重复星最近作为一个统一的中子星类别出现,通过剧烈的X射线和伽马射线爆发以及发光的X射线脉动来识别,两者都被认为是由巨大的内部磁场衰变提供动力。这种“磁星”假说提出了这些物体与传统旋转动力卫星(RPP)的物理关系的问题。因此,最高的磁场RPP可能是两个群体之间的过渡对象。最近报道的PSR J1846-0258类磁星爆发,以前被认为是纯粹的旋转动力,显然支持这一建议。在这里,我们回顾了已知的最高磁场RPP的观测特性,并显示了一些共同的特点,是值得注意的RPP之间,这是合理地与他们的高场。使用这些对象,我们认为在中子星的建议“磁热演化”的证据,并认为,虽然有些存在,它还不是决定性的。

英文摘要:

Anomalous X-ray pulsars and soft gamma repeaters have recently emerged as a unified class of neutron stars, identified by dramatic X-ray and gamma-ray outbursts and via luminous X-ray pulsations, both thought to be powered by the decay of an enormous internal magnetic field. This "magnetar" hypothesis has raised the question of these objects' physical relationship with conventional rotation-powered pulsars (RPPs). The highest magnetic-field RPPs might therefore be expected to be transition objects between the two populations. The recently reported magnetar-like outburst of PSR J1846-0258, previously thought to be purely rotation-powered, clearly supports this suggestion. Here we review the observational properties of the highest magnetic-field RPPs known, and show some common characteristics that are notable among RPPs, which are plausibly related to their high fields. Using these objects, we consider the evidence for proposed "magneto-thermal evolution" in neutron stars, and argue that while some exists, it is not yet conclusive.
