论文摘要
在ASAS目录中列出的$δ$> -30 $^\ Circ $中，在Eclips的二进制文件中确定了双二进制文件。除了文献中已知的双胞胎二进制文件外，已经确定了68个新系统，还进行了光度和光谱观测。已经得出并呈现了颜色，光谱类型，温度，半径和质量的质量。包括在ASA中存在的12个双二元系统和脱落二进制恒星的绝对参数目录中，总共已统计地研究了80个双支二进制二进制系统。双胞胎的光谱类型分布与ASAS数据库中脱落的二进制恒星的光谱类型分布表明，双胞胎的光谱类型分布与分离系统的光谱分布相似。该结果已被解释，因为双胞胎没有特殊的形成机制，而不是正常的分离二进制物。由于我们对HD〜154010的案例研究（双二元），我们介绍了系统的精确物理参数。
Twin binaries were identified among the eclipsing binaries with $δ$>--30$^\circ$ listed in the ASAS catalog. In addition to the known twin binaries in the literature, 68 new systems have been identified, photometric and spectroscopic observations were done. Color, spectral type, temperature, ratio of radii and masses of the components have been derived and presented. Including 12 twin binary systems that exist in both ASAS and the catalogue of absolute parameters of detached eclipsing binary stars, a total of 80 twin detached binary systems have been statistically studied. A comparison of the spectral type distribution of the twins with those of detached eclipsing binary stars in the ASAS database showed that the spectral type distribution of twins is similar to that of detached systems. This result has been interpreted as there is no special formation mechanism for twins than for normal detached binaries. As a result of our case study for HD~154010, a twin binary, we presented the precise physical parameters of the system.
