Abstract:
We present the detection of 1617 new transiting-planet candidates,
identified in the Transiting Exoplanet Survey Satellite (TESS)
full-frame images observed during the Primary Mission (Sectors 1-26).
These candidates were initially detected by the Quick-Look Pipeline
(QLP), which extracts full-frame image lightcurves for, and searches
all stars brighter than, TESS magnitude T=13.5mag in each sector.
However, QLP heavily relies on manual inspection for the
identification of planet candidates, limiting vetting efforts to
planet-hosting stars brighter than T=10.5mag and leaving millions of
potential transit signals unvetted. We describe an independent vetting
pipeline applied to QLP transit search results, incorporating both
automated vetting tests and manual inspection to identify promising
planet candidates around these fainter stars. The new candidates
discovered by this ongoing project will allow TESS to significantly
improve the statistical power of demographic studies of giant,
close-in exoplanets.
