cds-question@unistra.frstellar-associationsvisible-astronomybroad-band-photometryeffective-temperatureWalraven photometry is presented of established and probable members of the Scorpio-Centaurus OB association. For each star, effective temperature and surface gravity are derived using Kurucz atmosphere models (1979ApJS...40....1K). From the Straizys and Kuriliene (1981Ap&SS..80..353S) tables, absolute magnitudes are calculated. Distance moduli and visual extinctions are determined for all stars. From a comparison of the HR-diagrams of the stars in each subgroup with theoretical isochrones, the ages of the three subgroups are derived. The distances to the three subgroups are shown to be different; there is a general trend (also within each subgroup) for the distances to be larger at higher galactic longitudes. The visual extinction in the youngest subgroup Upper-Scorpius, is well correlated with the IRAS 100-micron map. The distance toward the Ophiuchus dark clouds is found to be 125 pc, based on the photometric distances to the stars. Most of the early-type stars in Upper-Scorpius are located at the far side of the dark clouds.1989A&A...216...44Dhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/216/44CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJS/82/117 : UBV and H-{beta} in Sco-Cen association (Slawson+, 1992)J/A+A/356/541 : T Tauri stars in the Sco-Cen OB association (Koehler+, 2000)J/A+A/448/1001 : Radial velocities of B stars in Sco-Cen (Jilinski+, 2006)J/AJ/124/1670 : Post-T Tauri Stars in Sco-Cen Association (Mamajek+, 2002)J/PAZh/33/643 : Kinematics of Sco-Cen OB Association (Bobylev+, 2007)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/216/44https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/216/44http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/216/44https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/216/44https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/216/44http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/216/44GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/216/44/table3 (Derived physical parameters for stars in the Sco-Cen association)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/216/44/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/216/44/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/216/44/table3?GETtext/xml+votable180.050000true171.0463639-72.25660780.0055555555555555565/10823 6/25048 30722 37145 37888 37894 37903 37905 37912 41516 41534 41584 41606-41607 41634 41692 41705 41709 41725 41866 41898-41899 41962-41963 41973 41979 41982-41983 42555-42556 42604 42606 42617-42618 42623 42628 42633 42640 42647 42652 42655-42658 42660-42661 42663 42672-42673 42677 42682 42684 42687 42694 42696 42698 42714 42720 42728 42730 42734 42736 42738 42740 42903 42905 42911 42924 42932 42934 42944 42947 42953 42955-42956 42959 42976-42977 42979-42982 42984-42985 42987-42990 42994 43018 43035 43038 43051 43056 43062 43067 43095 43099 43117 43137 43140 43183 43211 43224 43233 43238 43267 43272 43276 43286 43299-43300 43303 43307-43308 43313 43315 43321 43323 43333 43336 43338 43342 43345 43349 43359 43365 43369 43372 43376-43377 43383 43391 43397 43407 43412 43414 43416 43418-43420 43425 43429-43430 43440 43443-43444 43450 43457-43458 43460 43474 43483 43488 43495 43497 43516 43521 43531 43561 43794 43796 43843-43844 43852 44037 44039-44040 44043 44046 44051 44054 44059-44060 44068 44076 44085-44086 44088-44089 44093 44096 44098 44119 44160 44227 44293-44294 44299 44305-44306 44310 44312-44313 44316-44317 44319 44341 44349 44352 44354 44356-44357 44360 44363 44366 44368 44371 44378-44379 44384-44386 44389 44393 44436 445023.322582951404819e-19 3.852589004194616e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/216/44?format=asciiOpticaldefaultJ/A+A/216/44/table3Derived physical parameters for stars in the Sco-Cen associationrecnoRecord number assigned by the VizieR team.
