Abstract—

We have carried out a comparative analysis of the parameters of two samples of radio pulsars. The first of them is characterized by periods \(P > 2\) s, the second one—by the surface magnetic fields \({{B}_{s}} > 4.4 \times \) 10¹³ G. The purpose for selecting these values is for the understanding the origin of the difference between normal pulsars and anomalous X-ray pulsars (AXP) and gamma-repeaters (SGR) with similar values of the periods and magnetic fields. It is shown that the derivative dependence of the period on its value \(P\) in the long-period pulsars does not agree with the model of magneto-dipole braking and requires other mechanisms or the search for specific distributions of their parameters. In the pulsars with large magnetic fields and in AXP/SGR, this dependence does not contradict the magnetic dipole model. For pulsars with \(P > 2\) s, the transformation efficiency of the rotation energy into the observed radiation turns out to be several times higher than for the objects with shorter periods. The pulsars with long periods have, on average, two orders of magnitude larger age than the sources with \({{B}_{s}} > 4.4 \times \) 10¹³ G and AXP/SGR, and are, on average, located higher above the Galactic plane. It is concluded that the main physical parameters of the pulsars with large surface magnetic fields and their spatial distribution are close to the parameters and distribution of AXP/SGR. The comparison shows that it is not the rotation period, but the strong surface magnetic field is the decisive factor for the AXP/SGR peculiarity.

几种类型的脉冲星的参数比较

摘要-

我们对两个无线电脉冲星样本的参数进行了比较分析。其中第一个以周期\（P> 2 \） s为特征，第二个以表面磁场\（{{B} _ {s}}> 4.4 \ times \） 10 ¹³ G为特征。选择这些值是为了了解正常脉冲星与异常X射线脉冲星（AXP）和伽玛重复器（SGR）之间具有相似的周期和磁场值之间的差异。证明了周期对它的值\（P \）的导数依赖性在长周期脉冲星中，磁偶极子制动模型与磁偶极子制动模型不一致，因此需要其他机制或寻找其参数的特定分布。在具有大磁场的脉冲星中以及在AXP / SGR中，这种依赖性与磁偶极子模型并不矛盾。对于\（P> 2 \） s的脉冲星，旋转能量转化为观察到的辐射的转换效率比短周期物体的转换效率高出几倍。长周期的脉冲星的平均年龄比\（{{B} _ {s}}> 4.4 \ times \）的源大两个数量级10 ¹³G和AXP / SGR，平均而言，它们位于银河平面上方的较高位置。结论是，具有较大表面磁场的脉冲星的主要物理参数及其空间分布与AXP / SGR的参数和分布接近。比较表明不是旋转周期，而是强表面磁场是AXP / SGR特性的决定性因素。
