摘要

我们对初步候选的广义非共生双星中最后六颗位于北天的恒星进行了光谱研究，没有发现任何非共生的证据。因此，考虑到我们之前的研究发现了一个这样的双星系统，我们确认我们初步估计的太阳邻域中由俘获形成的双星的比例不超过0.03%。

Searching for wide binary stars with non-coeval components in the northern sky

We have spectroscopically studied the last six stars in the northern sky from our preliminary list of candidates for wide non-coeval pairs, and we have found no evidence of non-coevality. Thus, considering our previous research, which found one such binary system, we confirm that our preliminary estimate of the fraction of binaries in the solar neighborhood formed by capture is no more than 0.03%.
