cds-question@unistra.frmultiple-starsexoplanetsapparent-magnitudeastronomical-modelsNASA's Transiting Exoplanet Survey Satellite (TESS) presents us with an unprecedented volume of space-based photometric observations that must be analyzed in an efficient and unbiased manner. With at least ~1000000 new light curves generated every month from full-frame images alone, automated planet candidate identification has become an attractive alternative to human vetting. Here we present a deep learning model capable of performing triage and vetting on TESS candidates. Our model is modified from an existing neural network designed to automatically classify Kepler candidates, and is the first neural network to be trained and tested on real TESS data. In triage mode, our model can distinguish transit-like signals (planet candidates and eclipsing binaries) from stellar variability and instrumental noise with an average precision (the weighted mean of precisions over all classification thresholds) of 97.0% and an accuracy of 97.4%. In vetting mode, the model is trained to identify only planet candidates with the help of newly added scientific domain knowledge, and achieves an average precision of 69.3% and an accuracy of 97.8%. We apply our model on new data from Sector 6, and present 288 new signals that received the highest scores in triage and vetting and were also identified as planet candidates by human vetters. We also provide a homogeneously classified set of TESS candidates suitable for future training.2019AJ....158...25Yhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/158/25CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toIV/38 : TESS Input Catalog - v8.0 (TIC-8) (Stassun+, 2019)J/ApJ/809/77 : Transiting Exoplanet Survey Satellite (TESS) (Sullivan+, 2015)J/AJ/156/102 : TESS Input Catalog and Candidate Target List (Stassun+, 2018)J/ApJS/239/2 : Simulated exoplanets from TESS list of targets (Barclay+, 2018)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/158/25https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/158/25http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/158/25https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/158/25https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/158/25http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/158/25GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/158/25/table2 (New threshold-crossing events (TCEs) from Sector 6 with the highest likelihood of being planet candidates and manually assigned planet candidates (PC) labels)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/158/25/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/158/25/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/158/25/table2?GETtext/xml+votable180.050000true89.2356497-49.00693970.0055555555555555565/5235 6/20480 20499 20502 20566 20575 20579 20589 20613 20662 20682 20692 20707 20709 20710 20714 20741 20744 20745 20747 20755 20756 20758 20764 20766 20767 20769 20772 20780 20781 20784 20785 20787 20789 20790 20793 20798 20810 20833 20834 20835 20840 20843 20846 20847 20858 20864 20874 20881 20882 20906 20911 20926 20929 20933 20935 20936 20939 20952 20953 20954 20957 20959 20960 20961 20969 20970 20971 20973 20975 20977 20978 20979 20982 20989 21010 21011 21045 21062 21092 21093 21112 21114 21206 21251 21259 21263 21269 21271 21275 21276 21282 21293 21295 21299 21308 21312 21314 21315 21316 21319 21322 21327 21330 21332 21333 21337 21340 21346 21349 21357 21359 21360 21366 21368 21369 21403 21415 21431 21433 21435 21444 21446 21451 21666 21670 21675 21676 21678 21679 22016 22017 22021 22022 22801 22805 32862 32890 32980 32991 33049 33070 33073 33077 33078 33087 33092 33094 33112 33120 33124 33140 33143 33157 33164 33220 33241 33798 33823 33854 33868 33878 33890 33891 33895 33929 33984 34052 34068 34084 34089 34102 34109 34113 34120 34141 34171 34176 34193 34194 34195 34251 34264 34276 37484 37519 37533 37547 37548 37556 37578 37579 37581 37603 37610 38914 38936 38938 38946 38957 38964 38965 38968 38977 38980 38982 38983 39019 39022 39056 39058 39068 39078 39084 39085 39099 39136 39137 39150 39428 39433 39474 39475 39484 39487 39489 39503 39536 39538 39539 39547 39548 39550 39551 39565 39596 39599 39611 39637 39652 39673 39676 39677 39816 39846 39847 39855https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/158/25?format=asciidefaultJ/AJ/158/25/table2New threshold-crossing events (TCEs) from Sector 6 with the highest likelihood of being planet candidates and manually assigned planet candidates (PC) labelsSimbadNameSimbad column added by the CDSmeta.idcharrecnoRecord number assigned by the VizieR team.
