TESS Eclipsing Binaries ("TESS-EBs")

TESS-EBs is a catalog containing locations, ephemerides and basic light curve properties for eclipsing binary stars found in data from the Transiting Exoplanet Survey Satellite (TESS). Prša et al. 2022 discuss the selection criteria for eclipsing binary candidates, the detection of hither-to unknown eclipsing systems, the determination of ephemerides, the validation and triage process, and the derivation of heuristic estimates for the ephemerides. They also present statistical properties of the sample and qualitative estimates of completeness. Instead of keeping to the widely used discrete classes, the authors propose a binary star morphology classification based on a dimensionality reduction algorithm. The catalog will continue to be updated with new sectors of data as they become available. The deliverables presented here are curated by the TESS Eclipsing Binary Working Group, an open group of professional and citizen scientists.
