论文摘要

事实证明,测量脉动恒星中的相位调制是找到二进制系统的一种非常成功的方法。对此,称为Delta Scuti恒星的脉动脉冲序列A和F变量对此特别好,并且这些样品的样本几乎被完全利用。但是,某些\ textIt {kepler} $δ$ scuti星在恒星特性目录中的温度不正确,并且在先前的分析中被遗漏。我们使用自动脉动分类算法在数万f型恒星中找到93个新的$δ$ Scuti脉动脉冲,然后我们搜索了可归因于二元性的相位调制。我们发现了10个新的二元系统,并计算了它们的轨道参数,我们将其与以前以相同方式发现的二进制文件进行了比较。结果表明,一些新同伴可能是白矮人。

Measuring phase modulation in pulsating stars has proved to be a highly successful way of finding binary systems. The class of pulsating main-sequence A and F variables known as delta Scuti stars are particularly good targets for this, and the \textit{Kepler} sample of these has been almost fully exploited. However, some \textit{Kepler} $δ$ Scuti stars have incorrect temperatures in stellar properties catalogues, and were missed in previous analyses. We used an automated pulsation classification algorithm to find 93 new $δ$ Scuti pulsators among tens of thousands of F-type stars, which we then searched for phase modulation attributable to binarity. We discovered 10 new binary systems and calculated their orbital parameters, which we compared with those of binaries previously discovered in the same way. The results suggest that some of the new companions may be white dwarfs.
