脉冲星:宇宙永久“中性磁铁”?

Pulsars: Cosmic Permanent 'Neutromagnets'?

Johan Hansson, Anna Ponga

摘要:

我们认为,中子星可能是自旋极化的中子星,即宇宙永磁体。这将简单地解释关于磁星的几个观测事实,包括“信标效应”本身,即旋转轴和磁轴的静态/稳定不对准,脉冲的极端时间稳定性以及磁场强度的上限的存在-与“磁星”中观察到的一致。虽然我们的模型诚然是推测性的,但后一个事实在我们看来不太可能是纯粹的巧合。

英文摘要:

We argue that pulsars may be spin-polarized neutron stars, i.e. cosmic permanent magnets. This would simply explain several observational facts about pulsars, including the 'beacon effect' itself i.e. the static/stable misalignment of rotational and magnetic axes, the extreme temporal stability of the pulses and the existence of an upper limit for the magnetic field strength - coinciding with the one observed in "magnetars". Although our model admittedly is speculative, this latter fact seems to us unlikely to be pure coincidence.
