Abstract:
In this paper we present a catalog of 4584 eclipsing binaries observed
during the first two years (26 sectors) of the TESS survey. We discuss
selection criteria for eclipsing binary candidates, detection of
hitherto unknown eclipsing systems, determination of the ephemerides,
the validation and triage process, and the derivation of heuristic
estimates for the ephemerides. Instead of keeping to the widely used
discrete classes, we propose a binary star morphology classification
based on a dimensionality reduction algorithm. Finally, we present
statistical properties of the sample, we qualitatively estimate
completeness, and we discuss the results. The work presented here is
organized and performed within the TESS Eclipsing Binary Working
Group, an open group of professional and citizen scientists; we
conclude by describing ongoing work and future goals for the group.
Description:
The Transiting Exoplanet Survey Satellite (TESS) was launched in
2018-April; during its 2yr prime mission, it monitored ∼200,000 bright
stars for exoplanets across the sky with a 2 minute short cadence. In
addition, TESS acquired full-frame images (FFIs) every 30 minutes.
In this paper, the first in the TESS eclipsing binary (EB) series, we
present a sample of 4584 EBs observed by TESS in the first 26 sectors
of observation (Year 1 and 2: 2019-July-2020-July).

Note (1): Additional events that do not fold to the original ephemeris, or
background EBs that are detected in the same light curve, get a new
signal_id.
Note (2): Source is always "Light Curve File (LCF)" but future versions of
the catalog will contain Full Frame Image (FFI) sources as well.
Note (3): For morphological classification of the light curves, we rely on the
morphology parameter as defined in Matijevic+ (2012AJ....143..123M 2012AJ....143..123M).
The morphology parameter is defined as a continuous variable in the
range [0,1], where 0 corresponds to the widest detached systems and 1
to ellipsoidal variables. See Section 3.6.
