六颗晚型活动色球双星的轨道

Orbits of Six Late-type Active-Chromosphere Binaries

R. F. Griffin, N. Filiz Ak

摘要:

我们给出了活动恒星HD 82159(GS Leo)、HD 89959、BD +39 2587(HD 112733的伴星)、HD 138157(OX Ser)、HD 143705和HD 160934的光谱轨道。这篇论文是Galvez等人2006年发表在该杂志上的一篇论文的续集,具有类似的公开意图。他们只展示了图表,没有给出任何数据,除了周期(其中只有两个是正确的)和在某些情况下的偏心率之外,没有轨道要素。在这里,我们提供了所有恒星的完整信息和可靠的轨道要素,除了HD 160934,它还没有完成一个周期,因为它是第一次观察径向速度。

英文摘要:

We present spectroscopic orbits for the active stars HD 82159 (GS Leo), HD 89959, BD +39 2587 (a visual companion to HD 112733), HD 138157 (OX Ser), HD 143705, and HD 160934. This paper is a sequel to one published in this journal in 2006, with similar avowed intention, by Galvez et al.. They showed only graphs, and gave no data, and no orbital elements apart from the periods (only two of which were correct) and in some cases the eccentricities. Here we provide full information and reliable orbital elements for all the stars apart from HD 160934, which has not completed a cycle since it was first observed for radial velocity.
