论文摘要
2015年，开始进行径向速度监测活动，以重新确定和/或限制光谱二进制系统的轨道解决方案。观察结果是在大学天文台耶拿（Jena）与埃切尔光谱仪Flechas进行的。我们目标样本主要部分的结果已经发布。对于该广告系列的最终目标，$θ$ CEP，我们现在可以根据均匀覆盖的径向速度曲线提出轨道解决方案。与第9光谱二进制轨道目录中给定值相比，这种单线光谱二进制的周期事实证明明显更大，并且轨道比给定值更为偏心。
In 2015 a radial velocity monitoring campaign was started in order to redetermine and/or constrain the orbital solutions of spectroscopic binary systems. The observations were carried out at the University Observatory Jena with the Échelle spectrograph FLECHAS. The results from the main part of our target sample are already published. For the final target of this campaign, $θ$ Cep, we can now present an orbital solution based on a homogeneously covered radial velocity curve. The period of this single-lined spectroscopic binary turns out to be significantly larger and the orbit is much more eccentric compared to the given values in the 9th Catalogue of Spectroscopic Binary Orbits.
