cds-question@unistra.frx-ray-sourcesyoung-stellar-objectsinfrared-photometryX-rays from very young stars are powerful probes to investigate the mechanisms at work in the very first stages of the star formation and the origin of X-ray emission in very young stars. We present results from a 500ks long observation of the rho Ophiuchi cloud with a XMM-Newton large program named DROXO, aiming at studying the X-ray emission of deeply embedded young stellar objects (YSOs).2010A&A...519A..34Phttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/519/A34CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/359/113 : X-ray and IR study of rho Oph dark cloud (Grosso+, 2000)J/ApJS/112/109 : rho Oph Near IR Positions and Photometry (Barsony+, 1997)J/A+A/372/173 : ISOCAM observations of the rho Ophiuchi cloud (Bontemps+ 2001)J/A+A/452/245 : Near-IR photometry of PMS stars in rho Oph (Natta+, 2006)J/A+A/485/155 : HK photometry of rho Oph PMS stars (Alves de Oliveira+, 2008)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/519/A34https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/519/A34http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/519/A34https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/519/A34https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/519/A34http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/519/A34GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/519/A34/tablea1 (List of sources detected in the DROXO EPIC images)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/519/A34/tablea1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/519/A34/tablea1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/519/A34/tablea1?GETtext/xml+votable180.050000true246.580833-24.6247220.005555555555555556Cone search capability for table J/A+A/519/A34/tablea3 (ISOCAM YSOs (Bontemps et al. 2001, J/A+A/372/173) undetected in the DROXO field of view)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/519/A34/tablea3?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/519/A34/tablea3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/519/A34/tablea3?GETtext/xml+votable180.050000true246.62875-24.5186110.0055555555555555566/429812.4016587514425055e-21 6.185923063528282e-20https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/519/A34?format=asciiX-rayInfrareddefaultJ/A+A/519/A34/tablea1List of sources detected in the DROXO EPIC imagesrecnoRecord number assigned by the VizieR team.
