cds-question@unistra.freclipsing-binary-starsspectroscopic-binary-starsphotometryvisible-astronomyMassive stars play a crucial role in the cosmic dynamics and chemical evolution of galaxies. Despite their significance, our understanding of their evolution and properties remains limited. An accurate determination of stellar parameters, such as the mass and radius, is essential for advancing our knowledge. Detached eclipsing binaries (DEBs) are particularly valuable for these determinations due to the minimal interaction between their stellar components, allowing for precise measurements. This study aims to introduce the Young Massive Detached Binary (YMDB) catalog, designed to address the gap in the highprecision absolute parameter determination for young massive stars. By focusing on DEBs within the spectral range O9-B1, this catalog seeks to provide a reliable database for future astronomical studies and improve our understanding of massive star evolution. We conducted a photometric analysis of 87 young massive stars in detached eclipsing systems using TESS light curves (LCs) that were processed through a custom pipeline. This analysis involved determining the amplitude of magnitude variations, orbital periods, times of minima, eccentricities, and the presence of apsidal motion and heartbeat phenomena. A thorough literature review was performed to obtain MK spectral classifications. We performed our own spectral classification of 19 systems to support the sample where a new classification was lacking or inconclusive. The analysis identified 20 previously unreported binary systems, with 13 newly recognized as variable stars. Among the 87 stars examined, 30 are confirmed as YMDB members, and 25 are candidates pending spectral classification. The exclusion of the remaining 32 stars is attributed to unsuitable spectral types or their nondetached binary nature. Notable findings include the identification of new LC classifications, eccentricities in 13 systems, and heartbeat phenomena in several targets. The YMDB catalog oers a resource of high-quality LCs and reliable stellar classifications, serving as a valuable tool for the astronomical community.2024A&A...690A.306Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/690/A306CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/690/A306https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/690/A306http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/690/A306https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/690/A306https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/690/A306http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/690/A306GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/690/A306/table1 (Confirmed systems in the YMDB catalog)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/690/A306/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/690/A306/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/690/A306/table1?GETtext/xml+votable180.050000true0.542666767.42921940.005555555555555556Cone search capability for table J/A+A/690/A306/table2 (Candidates systems in the YMDB catalog)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/690/A306/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/690/A306/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/690/A306/table2?GETtext/xml+votable180.050000true0.54287567.40895280.005555555555555556Cone search capability for table J/A+A/690/A306/table3 (Unqualified systems in the YMDB catalog)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/690/A306/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/690/A306/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/690/A306/table3?GETtext/xml+votable180.050000true48.5222559.56346940.0055555555555555566/1335 1379 1386 2941 3283 3640 3755 9478 12991 13281 14255 14358 14409 14459 14693 14754 15486 15683 15713 15808 20808 21635 22080 22088 22122 22837 22862 22992 22994 24555 28746 28803 28810 37247 37333-37334 37746 37755 37825 37839 37854 37869 37894-37895 37899 37903 37906 37914 37923 37931-37932 37952 38016 38018 38023 39075 39208 39250 39384 39774 39798 40456 41589 41630 41646 41662 41756 41758 41813 42382 42394 42405 42496 42516 43027-43029https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/690/A306?format=asciiOpticaldefaultJ/A+A/690/A306/table1Confirmed systems in the YMDB cataloge_T0Time error (BTJD) for T0dstat.errordoublerecnoRecord number assigned by the VizieR team.
