摘要

摘要我们分析了对毫秒脉冲星 B0329+54 (J0332+5434)的观测结果，该脉冲星的重心到达时间（TOAs）在长时间尺度上呈现准周期性变化。我们检验了以前提出的关于该脉冲星周围存在一颗质量接近于地球行星质量、轨道周期为 27.8 年的行星的假说，以解释其 TOAs 的变化。我们的研究表明，考虑到 1968-2022 年整个观测时间间隔内的 TOA 残差序列，这一假设并没有得到证实，而且这颗脉冲星的 TOA 变化显然有着不同的物理原因。

Testing the Hypothesis about the Existence of a Planet Orbiting the Pulsar B0329+54 (J0332+5434)

We have analyzed the results of our observations of the millisecond pulsar B0329+54 (J0332+5434), which exhibits quasi-periodic variations in the barycentric times of arrival (TOAs) of pulses on long time scales. We have tested the hypothesis about the existence of a planet with a mass close to the mass of the terrestrial planets and an orbital period of 27.8 yr around this pulsar that was proposed previously to explain the variations in its TOAs. We show that this hypothesis is not confirmed when considering the series of TOA residuals over the entire available time interval of observations 1968–2022 and that the TOA variations for this pulsar apparently have a different physical cause.
