论文摘要
给出了长期观察到脉冲星B0950+08的结果。这些观察结果是在2016年1月至2019年5月(450天)的LPA射电望远镜上以111 MHz的频率进行的。已经检测到该脉冲星的发射差异很强,信号与噪声比的变化数百次。一部分长期通量密度可变性可以通过星际介质中的折射闪烁来解释。确认了螺栓(IP)和主脉冲(MP)之间的辐射存在。它比高频更强大。我们在2017年8月1日检测到了异常的插插和前体(PR)辐射。在强65个插孔的底部,我们发现IP和PR的能量之间以及IP的相位与距离PR-IP之间的相关性。结果表明,可以在对齐旋转器模型的框架中解释该脉冲星的观察到的特殊性。我们估计了辐射水平距中子恒星中心的距离。初始期限为0.2秒的计算值意味着并非所有脉冲星都有毫秒的天生。 PULSAR的较大年龄(6.8千年)及其磁矩与旋转轴(小于20 $^{\ Circ} $)之间的小角度证实了对脉冲星演变对比对的建议。
Results of long time observations of the pulsar B0950+08 are given. These observations were carried out at the LPA radio telescope at the frequency of 111 MHz from January of 2016 to May of 2019 (450 days). A strong variability in emission of this pulsar has been detected with changes of signal to noise ratios hundreds of times. Part of the long-time flux density variability can be explained by refractive scintillations in the interstellar medium. The existence of radiation between the interpulse (IP) and main pulse (MP) was confirmed. It was more powerful than at high frequencies. We detected the unusual interpulse and precursor (Pr) radiation on August 1, 2017. On the base of strong 65 interpulses we found the correlations between energies of IP and Pr and between the phase of IP and the distance Pr-IP. It is shown that the observed peculiarities of this pulsar can be explained in the frame of the aligned rotator model. We estimated distances of radiation levels from the center of the neutron star. The calculated value of the initial period of 0.2 sec means that not all pulsars are born with millisecond periods. The large age of the pulsar (6.8 millions of years) and the small angle between its magnetic moment and the rotation axis (less than 20$^{\circ}$) confirm the suggestion on the pulsar evolution to an alignment.
