可视化二进制文件的统计研究

Statistical Study of Visual Binaries

H. I. Abdel-Rahman, M. I. Nouh, W. H. Elsanhoury

摘要:

本文研究了双星表中宽双星对的一些统计分布。对视觉二进制的一些基本参数导出了频率分布和检验假设。结果表明,发现震级差呈指数分布,这意味着所选系统的大部分分量具有相同的光谱类型。质量比的分布集中在0.7左右,符合Salpeter质量函数。的线性分离的分布似乎是指数,这与以前的研究紧密的双星。

英文摘要:

In this paper, some statistical distributions of wide pairs included in Double Star Catalogue are investigated. Frequency distributions and testing hypothesis are derived for some basic parameters of visual binaries. The results reached indicate that, it was found that the magnitude difference is distributed exponentially, which means that the majority of the component of the selected systems is of the same spectral type. The distribution of the mass ratios is concentrated about 0.7 which agree with Salpeter mass function. The distribution of the linear separation appears to be exponentially, which contradict with previous studies for close binaries.
