Abstract:
The Transiting Exoplanet Survey Satellite (TESS) has surveyed nearly
the entire sky in full-frame image mode with a time resolution of 200s
to 30 minutes and a temporal baseline of at least 27 days. In addition
to the primary goal of discovering new exoplanets, TESS is
exceptionally capable at detecting variable stars, and in particular
short-period eclipsing binaries, which are relatively common, making
up a few percent of all stars, and represent powerful astrophysical
laboratories for deep investigations of stellar formation and
evolution. We combed Sectors 1-82 of the TESS full-frame image data
searching for eclipsing binary stars using a neural network that
identified ∼1.2 million stars with eclipse-like features. Of these, we
have performed an in-depth analysis on ∼60,000 targets using automated
methods and manual inspection by citizen scientists. Here we present a
catalog of 10,001 uniformly vetted and validated eclipsing binary
stars that passed all our ephemeris and photocenter tests, as well as
complementary visual inspection. Of these, 7936 are new eclipsing
binaries while the remaining 2065 are known systems for which we
update the published ephemerides. We outline the detection and
analysis of the targets, discuss the properties of the sample, and
highlight potentially interesting systems. Finally, we also provide a
list of ∼900,000 unvetted and unvalidated targets for which the neural
network found eclipse-like features with a score higher than 0.9, and
for which there are no known eclipsing binaries within a sky-projected
separation of a TESS pixel (∼21").
