论文摘要

本文提供了76``b''的发射光束结构的分析,称为Arecibo Sky中的脉冲星。这些对象大多数都包含在古尔德和洛法和洛法尔高带调查中,因此补充了我们对这些人群的各个部分的其他作品。这些包括我们在这里的Arecibo Sky中大多数研究的脉冲星,与Olszanski et.al中的脉冲星类似。并扩展我们在两项调查中研究所有脉冲星的总体努力。这些分析基于327 MHz和1.4 GHz的Arecibo望远镜进行的观察结果。使用Lofar或Pushchino射电天文台,在频率下降到100 MHz的频率下,以及较低的较长波长阵列的少数观察到了许多。这项工作使用Arecibo观测作为解释低频轮廓和发射光束几何形状的基础。我们尝试使用核心/双锥拓扑来构建定量的几何发射光束模型,同时回顾以前的研究和论证的证据,以了解这些来源的先前分类。除两个脉冲星以外,所有努力都是成功的,并且在许多对象中都确定了有趣的新子渗透调制模式。我们在``B'pulsars''的整个人群的背景下解释了Arecibo Pulsar种群。

This paper provides analyses of the emission beam structure of 76 ``B''-named pulsars within the Arecibo sky. Most of these objects are included in both the Gould & Lyne and LOFAR High Band surveys and thus complement our other works treating various parts of these populations. These comprise a further group of mostly well studied pulsars within the Arecibo sky that we here treat similarly to those in Olszanski et.al. and extend our overall efforts to study all of the pulsars in both surveys. The analyses are based on observations made with the Arecibo Telescope at 327 MHz and 1.4 GHz. Many have been observed at frequencies down to 100 MHz using either LOFAR or the Pushchino Radio Astronomy Observatory as well as a few with the Long Wavelength Array at lower frequencies. This work uses the Arecibo observations as a foundation for interpreting the low frequency profiles and emission-beam geometries. We attempt to build quantitative geometric emission-beam models using the core/double-cone topology, while reviewing the evidence of previous studies and arguments for previous classifications on these sources. These efforts were successful for all but two pulsars, and interesting new subpulse modulation patterns were identified in a number of the objects. We interpret the Arecibo pulsar population in the context of the entire population of ``B'' pulsars.
