cds-question@unistra.frexoplanetsvisible-astronomyThe Transiting Exoplanet Survey Satellite (TESS) mission measured light from stars in ~75% of the sky throughout its 2yr primary mission, resulting in millions of TESS 30-minute-cadence light curves to analyze in the search for transiting exoplanets. To search this vast data trove for transit signals, we aim to provide an approach that both is computationally efficient and produces highly performant predictions. This approach minimizes the required human search effort. We present a convolutional neural network, which we train to identify planetary transit signals and dismiss false positives. To make a prediction for a given light curve, our network requires no prior transit parameters identified using other methods. Our network performs inference on a TESS 30-minute-cadence light curve in ~5ms on a single GPU, enabling large-scale archival searches. We present 181 new planet candidates identified by our network, which pass subsequent human vetting designed to rule out false positives. Our neural network model is additionally provided as open-source code for public use and extension.2021AJ....161..273Ohttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/161/273CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/345 : Gaia DR2 (Gaia Collaboration, 2018)IV/38 : TESS Input Catalog - v8.0 (TIC-8) (Stassun+, 2019)J/ApJ/809/77 : Transiting Exoplanet Survey Satellite (TESS) (Sullivan+, 2015)J/MNRAS/465/2634 : Kepler and K2 best candidates for planets (Armstrong+, 2017)J/AJ/153/211 : Differential photometry of the F-subgiant HAT-P-67 (Zhou+,2017)J/ApJS/239/2 : Simulated exoplanets from TESS list of targets (Barclay+, 2018)J/AJ/156/102 : TESS Input Catalog and Candidate Target List (Stassun+, 2018)J/AJ/157/124 : DAVE.
