cds-question@unistra.frpre-main-sequence-starsx-ray-sourcesinfrared-photometryvisible-astronomybroad-band-photometryWe studied X-ray emission from young stars by analyzing the deep XMM-Newton observations of two regions of the Upper Scorpius association with an age of 5Myr. Based on near infrared and optical photometry we identified 22 Upper Scorpius photometric members among the 224 detected X-ray sources. We derived coronal properties of Upper Scorpius stars by performing X-ray spectral and timing analyses. The study of four strong and isolated stellar flares allowed us to derive the length of the flaring loops.2006A&A...459..199Ahttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/459/199CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/459/199https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/459/199http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/459/199https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/459/199https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/459/199http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/459/199GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/459/199/tableb1 (Sources detected in the CTIO observations)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/459/199/tableb1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/459/199/tableb1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/459/199/tableb1?GETtext/xml+votable180.050000true238.914583-24.1066110.005555555555555556Cone search capability for table J/A+A/459/199/tablec1 (Sources detected in the Danish 1.54m observations)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/459/199/tablec1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/459/199/tablec1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/459/199/tablec1?GETtext/xml+votable180.050000true238.824167-24.1531670.005555555555555556Cone search capability for table J/A+A/459/199/tabled1 (Sources detected in the XMM observations)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/459/199/tabled1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/459/199/tabled1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/459/199/tabled1?GETtext/xml+votable180.050000true239.051667-23.851250.0055555555555555565/11079 6/42990 44310 44313 44356 44360 443628.650015785639275e-20 1.7003137259100215e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/459/199?format=asciiX-rayOpticalInfrareddefaultJ/A+A/459/199/tableb1Sources detected in the CTIO observationsrecnoRecord number assigned by the VizieR team.
