Searching for eclipsing binaries in the GSFC-Eleanor-Lite database.

Abstract

This paper presents the discovery of 66 new eclipsing binaries using a 2-algorithm data pipeline from sector 3 of the GSFC-eleanor-lite database. This database, which contains eleanor- processed full-frame image light curves, was analyzed with a pipeline consisting of two algorithms: ECLIPSR and BLS. In the paper, I present details on the pipeline and the methods used to verify the existence of the eclipsing binaries. I also provide a catalog of the 66 new eclipsing binaries, including the properties measured by the two algorithms. In comparison with the majority of other papers, this pipeline is faster, consisting of per-light-curve runtimes of approximately one second, while still delivering accurate detections. Finally, this work also identifies a lower eclipsing binary density in the GSFC-eleanor-lite database compared with most short cadence photometry analyses but it simultaneously has a higher percentage of new eclipsing binaries as opposed to reconfirming previously discovered ones.
