cds-question@unistra.freclipsing-binary-starsvisible-astronomyorbitsWe present a catalogue of the Transiting Exoplanet Survey Satellite (TESS) targets that show multiple eclipses. In all of these stars, we detected two sets of eclipses, for which their two distinctive periods can be derived. These multiple stellar systems could either be doubly eclipsing quadruples or triple-star coplanar systems showing eclipses on the outer orbit in addition to the inner eclipses. In total, 116 systems were found to be doubly eclipsing, while 25 stars were identified as triply eclipsing triples. Several confirmed blends of two close sources were not included in our analysis. All these systems were identified by scanning the known eclipsing systems taken from the Variable Star Index database and checking their TESS light curves. The average period of the dominant pair, pair A, is 2.7 days in our sample, while for the second pair, pair B, the average period is 5.3 days. Several systems show evident eclipse timing variation (ETV) changes even from the short interval of the TESS data, indicating possible period changes and short mutual orbit. We also present evidence that the system V0871 Cen is probably a septuple-star system of architecture (Aa-Ab)-B-C-D. Most of the presented systems are adequately bright and show deep enough eclipses for observing, and therefore we call for new ground-based observations for these extremely interesting multiples. Owing to this motivation, we have included also the ephemerides for both pairs of each system, our catalogue also contains their depths of eclipses and the light-curve shapes as extracted from the TESS data. These new ground-based observations would be very useful for further derivation of the mutual movement of both pairs on their orbit via detection of the ETVs of both pairs for example.2022A&A...664A..96Zhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/664/A96CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/vsx : AAVSO International Variable Star Index VSX (Watson+, 2006-)IV/38 : TESS Input Catalog - v8.0 (TIC-8) (Stassun+, 2019)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/664/A96https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/664/A96http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/664/A96https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/664/A96https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/664/A96http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/664/A96GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/664/A96/table1 (Triply eclipsing triple candidates)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/664/A96/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/664/A96/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/664/A96/table1?GETtext/xml+votable180.050000true67.815208357.75031110.005555555555555556Cone search capability for table J/A+A/664/A96/tablea1 (Doubly eclipsing candidates)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/664/A96/tablea1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/664/A96/tablea1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/664/A96/tablea1?GETtext/xml+votable180.050000true0.693291769.873550.0055555555555555566/1301 1304 1317 1979 2004 3031 3066 3138 3176 3264 3273 3290 3311 3332 3436 3605 3615 3629 3726 3770 3846 4644 6653 9304 9661 9831 10534 10760 12795 13030 13306 13715 14264 14268 14298 14321 14406 14426 14430 14438 14549 14563 14567 14597 14641 14643 14646 14757 15396 15409 15435 15447 15492 15539 15600 15617 15630 15645 16031 16350 20792 20851 20861 20948 21370 21504 21649 21702 22043 22083 22145 22231 22296 23560 23699 23834 23839 23939 25411 32070 36991 37077 37204 37211 37334 37360 37458 37660 37734 37893 37895 37897 37901 37910 37923 37928 38033 38041 38065 38307 38462 39351 39355 39375 39686 39734 39777 39890 39938 39970 39980 40854 41042 41174 41190 41197 41288 41361 41649 41656 41737 42173 42238 42257 42326 42452 42489 42510 42529 42584 42600 43019 43040 43125 45225 45576 47295 47765 47774 47850https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/664/A96?format=asciiOpticaldefaultJ/A+A/664/A96/table1Triply eclipsing triple candidatesVSXVSX Target namemeta.id;meta.maincharrecnoRecord number assigned by the VizieR team.
