摘要:

我们已经搜索了K2活动0的光变曲线变化与恒星的变化数据。搜索结果以星表的形式呈现,给出了数据集中近2500颗变星的标识符。我们列出了检测到的变化范围、周期性(如果相关)和半振幅。光变曲线分为严格周期、准周期和非周期三种。我们并不试图确定变化的来源,它可能来自脉动或恒星活动。然而,我们交叉匹配的对象对变星相关的客人观察员的建议,在许多情况下指定变量类型。目前食双星不包括在内。未来的版本将解决每个K2字段,因为它是可用的,并可能进行改进,以包括更详细的目录信息。去除趋势的物体光变曲线现在可以从目录网站下载。

英文摘要:

We have searched the K2 campaign 0 data for lightcurve variations associated with stellar variability. The results of this search are presented as a catalogue, giving the identifiers of nearly 2500 variable stars in the dataset. We list the detected range of the variation, periodicity if relevant and semi-amplitude. Lightcurves are classified into strictly periodic, quasi-periodic and aperiodic groups. We do not attempt to identify the source of variability, which may arise from pulsation or stellar activity. However, we cross match the objects against variable star related guest observer proposals, specifying the variable type in many cases. At present eclipsing binary stars are not included. Future releases will address each K2 field as it is made available, and may be improved to include more detailed catalogue information. Detrended object lightcurves are now available for download from the catalogue website.
