论文摘要
PSR J0726-2612的旋转特性和X射线光度接近昏暗的中子星（XDIN）。有人提出，源可以是第一个具有可观察到的脉冲无线电发射的XDIN。我们已经研究了来源在后备光盘模型中测试这种可能性的长期演变。合理的模型曲线可以说明PSR J0726-2612的演变，其无线电脉冲星的属性与具有偶极场强度的高B无线电脉冲星的演变相似，$ b_0 \ sim $ b_0 \ sim $ \ sim $ \ times 10^{12}}〜$ g在恒星的极点。在同一模型中，Xdins估计具有相对较弱的字段（$ B_0 \ Lessim 10^{12}〜$ G），将它们远低于Pulsar死亡线。从模拟中，我们估计PSR J0726-2612的年龄为$ t \ sim 5 \ times 10^4〜 $ yr，并且将在$ \ sim 10^5〜 $ yr内实现普通无线电脉冲星的旋转属性，而不是xdin属性。
The rotational properties and X-ray luminosity of PSR J0726-2612 are close to those of dim isolated neutron stars (XDINs). It was proposed that the source could be the first XDIN with observable pulsed radio emission. We have investigated the long-term evolution of the source to test this possibility in the fallback disc model. Reasonable model curves that can account for the evolution of PSR J0726-2612 consistently with its radio pulsar property are similar to those of high-B radio pulsars with dipole field strength $B_0 \sim$ a few $\times 10^{12}~$G at the pole of the star. In the same model, XDINs are estimated to have relatively weak fields ($B_0 \lesssim 10^{12}~$G) locating them well below the pulsar death line. From the simulations, we estimate that PSR J0726-2612 is at an age of $t \sim 5 \times 10^4~$yr, and will achieve the rotational properties of a normal radio pulsar within $\sim 10^5~$yr, rather than the XDIN properties.
