摘要

本文介绍了从1978年至2017年普什奇诺天文台获得的脉冲星计时数据和当前观测数据对脉冲星旋转规律的分析结果。到达时间数值序列的参数逼近收敛多项式序列定义了数值的组合,这些数值对每个脉冲星都是唯一的,在任何参考系统中都是相同的,与脉冲星周期辐射的相干性相对应的观测时间长短无关。所有观测到的脉冲星的制动指数均为n =−(0.9±0.2),对应于旋转减速的单调性(>0)。在观测到的旋转参数中计算的间隔的多项式幂级数代表了一个解析的时间尺度,在这个时间尺度上计算了与旋转无关的观测间隔的变化,如脉冲星B1919+21和B0809+74,或者定义了超新星遗迹中脉冲星运动的不可预测的间隔变化,如PSR B0531+21或PSR B1822-09,它们的自发运动也不排除它属于超新星遗迹。

Compatibility of the Observed Rotation Parameters of Radio Pulsars on Long Time Scales
We present the results of an analysis of the rotation regularities of pulsars from the current observations and retrospective data on the timing of pulsars at Pushchino Observatory, obtained since 1978 to 2017. Parametric approximation of numerical series of Times of Arrival (ToAs) the convergence polynomial series defined the combinations of numerical values, unique for each pulsar, identical in any reference system for coinciding epochs, irrespective of duration of observations that corresponds to the coherence of periodic radiation of pulsars. The braking index at all observed pulsars is n =−(0.9 ± 0.2) that corresponds monotony of slowing down of rotation (>0). The polynomial power series of the intervals calculated in observed parameters of rotation represent an analytical time scale on which variations of observed intervals, uncorrelated with rotation, are counted, as at pulsars B1919+21 and B0809+74, or the unpredictable variations of intervals defining the movement of a pulsar in the supernova remnants, as at PSR B0531+21 or at PSR B1822-09 which spontaneous movement also doesn’t exclude its belonging to the supernova remnants.
