Direct and low-dispersion objective prism plates taken with the 1.2m UK Schmidt Telescope have been digitized by the SuperCOSMOS machine. Star counts have been performed for our region in selected luminosity slices in the U filter and isodensity contours have been used to identify the structures with enhanced stellar number density. We find evidence of triggered star formation from massive stars of older to more recent OB associations. Circular arcs constructed by O and B stars have been detected. A study of the population places stars with more recent ages in the groups of the arcs than of their centers. These effects can be explained by supernova explosions. A catalogue of the non-saturated detected OB stars in this region is given.2004A&A...423..919Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/423/919CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJS/101/41 : SMC and Bridge extended catalog (Bica+ 1995)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/423/919https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/423/919http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/423/919https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/423/919https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/423/919http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/423/919GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/423/919/table2 (Detected objects in our region according Bica & Schmitt (1995, Cat. <J/ApJS/101/41>))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/423/919/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/423/919/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/423/919/table2?GETtext/xml+votable180.050000true18.21667-73.119440.005555555555555556Cone search capability for table J/A+A/423/919/table3 (Detected (non-saturated) OB stars in our region)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/423/919/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/423/919/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/423/919/table3?GETtext/xml+votable180.050000true19.74167-73.624440.0055555555555555566/33296 33298-33299 33304-33305https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/423/919?format=asciiOpticaldefaultJ/A+A/423/919/table2Detected objects in our region according Bica & Schmitt (1995, Cat. <J/ApJS/101/41>)recnoRecord number assigned by the VizieR team.
