The Discovery of New Binary Systems Using Value-added Catalogs and TESS Data

Abstract

Using potentially variable sources flagged in value-added catalogs created by combining data from the Gaia, IPHAS, and KIS surveys, we utilized data from TESS, McDonald Observatory, and the Southern Plains Private Observatory to confirm and identify four of these potentially variable sources as eclipsing binaries. Combining large data sets and obtaining smaller-scale, focused observations allowed for the discovery of these systems, and shows the importance of both large value-added catalogs as well as targeted observations as follow up.
