摘要

开普勒像素项目的目标是在最初开普勒任务的单个像素中发现新的脉动和其他类型的变星。在该项目的框架中，在背景像素中识别了1272个食二进制候选点。在排除误报和那些已经出现在开普勒食双星表中的恒星后，我们剩下了776个新的食双星。这是对星表中2922个食双星的重要补充。我们介绍了我们所采用的方法，对选定的新发现的变星的4年(Q1-Q17)光曲线进行了检验。应用的方法是自动的，因此它们可以在未来用于探索其他太空任务(例如TESS，后来的PLATO)产生的大量数据。

Eclipsing binaries hiding in the background: the Kepler Pixel Project.

The aim of the Kepler Pixel Project is to discover new pulsating and other types of variable stars in the individual pixels of the original Kepler mission. In the framework of the project, 1272 eclipsing binary candidates were identified in the background pixels. After eliminating false positives and those stars that are already present in the Kepler Eclipsing Binary Catalog, we were left with 776 new eclipsing binaries. This is a substantial and significant addition to the 2922 eclipsing binaries present in the catalog. We present the methods we applied, examine the 4-year (Q1-Q17) light curves of selected newly found variable stars. The applied methods are automatic, therefore they can be used in the future to explore the vast amounts of data produced by other space missions (e.g. TESS, later PLATO).
