The cutting-edge tools used in this project allow us to measure the real flux of stars in dense fields, minimizing the effects due to contamination by neighbour sources. We extracted about 200000 light curves of stars in 645 open clusters located in the Southern ecliptic hemisphere and observed by TESS during the first year of its mission. We searched for transiting signals and we found 33 objects of interest, 11 of which are strong candidate exoplanets. Because of the limited SNR, we did not find any Earth or super-Earth. We identified two Neptune-size planets orbiting stars with R*<1.5R_{sun}_, implying a frequency f*=1.3+/-0.95 per cent consistent with the frequency around field stars. The seven Jupiter candidates around stars with R*<1.5R_{sun}_ imply a frequency f*=0.19+/-0.07 per cent, which is smaller than in the field. more complete estimate of the survey completeness and false positive rate is needed to confirm these results. Light curves used in this work will be made available to the astronomical community on the Mikulski Archive for Space Telescope under the project PATHOS.2020MNRAS.495.4924Nhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/495/4924CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/345 : Gaia DR2 (Gaia Collaboration, 2018)IV/38 : TESS Input Catalog - v8.0 (TIC-8) (Stassun+, 2019)J/MNRAS/490/3806 : Exoplanets & variable stars in 47 Tuc (Nardiello+, 2019)J/MNRAS/498/5972 : Variables & dippers in young associations (Nardiello, 2020)https://archive.stsci.edu/hlsp/pathos : PATHOS Home Pagehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/495/4924https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/495/4924http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/495/4924https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/495/4924https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/495/4924http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/495/4924GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/495/4924/table1 (Cluster parameters)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/495/4924/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/495/4924/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/495/4924/table1?GETtext/xml+votable180.050000true232.375-51.20833330.005555555555555556Cone search capability for table J/MNRAS/495/4924/table2 (Star parameters and priors for the modelling)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/495/4924/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/495/4924/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/495/4924/table2?GETtext/xml+votable180.050000true134.3845-47.84770.0055555555555555566/20957 21520 21523 21526 21682 21774 22869 22871 37227 37230-37231 37313 37351 37592-37594 37724 37788-37789 37821 37861 37897 37899 37933 39257 39760 39775 39789 41455 41466 41671 41688 41768 41829 41846 42207 42229 42470 43044https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/495/4924?format=asciiOpticaldefaultJ/MNRAS/495/4924/table1Cluster parametersSimbadNameSimbad column added by the CDSmeta.idchar_RARight Ascension (J2000) from SIMBAD (not part of the original data)degpos.eq.ra;meta.mainrecnoRecord number assigned by the VizieR team.
