论青年人与老年人降转行为的一致性

On the consistency of the spindown behavior of young and old pulsars

Mark G. Alford, Kai Schwenzer

摘要:

我们研究了由引力波辐射引起的中子星的自旋降速,发现如果r模饱和振幅足够大,则中子星中的r模可以定量地解释年轻中子星低的旋转频率。相反,对于如此大的饱和振幅,旧的强子毫秒双星的自旋下降速度要比观测到的快得多。我们讨论了这种明显的差异,可以使这种机制与观测数据一致的决议。

英文摘要:

We study the spindown of pulsars due to gravitational wave emission and show that r-modes in neutron stars provide a quantitative explanation for the observed low rotation frequencies of young pulsars if the r-mode saturation amplitude is sufficiently large. In contrast for such large saturation amplitudes old hadronic millisecond pulsars would spin down much faster than observed. We discuss resolutions of this apparent discrepancy that could make this mechanism consistent with the observational data.
