论文摘要
我们从光谱分类中估计了视觉二进制组的组成部分。我们选择了对，其中较小的组件看起来越来越多。进行了一些此类对的光谱观察结果，并且至少一对HD 〜156331被证实具有不同年龄的组成部分。由于质量交换在宽阔的二进制文件中被排除在外，这意味着可以通过捕获形成HD〜156331。
We have estimated masses of components of visual binaries from their spectral classification. We have selected pairs, where the less massive component looks more evolved. Spectral observations of some of such pairs were made, and at least one pair, HD~156331, was confirmed to have components of different age. Since mass exchange is excluded in wide binaries, it means that HD~156331 can be formed by the capture.
