cds-question@unistra.frh-ii-regionsyoung-stellar-objectsinfrared-photometryWe present here a follow-up study of the molecular gas and dust in the environs of the star forming region NGC 3503. This study aims at dealing with the interaction of the HII region NGC 3503 with its parental molecular cloud, and also with the star formation in the region, that was possibly triggered by the expansion of the ionization front against the parental cloud. To analyze the molecular gas we use CO(J=2-->1), ^13^CO(J=2-->1), C^18^O(J=2-->1), and HCN(J=3-->2) line data obtained with the on-the-fly technique from the APEX telescope. To study the distribution of the dust, we make use of unpublished images at 870um from the ATLASGAL survey and IRAC-GLIMPSE archival images. We use public 2MASS and WISE data to search for infrared candidate young stellar objects (YSOs) in the region.2014A&A...565A..30Dhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/565/A30CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toV/114 : MSX6C Infrared Point Source Catalog (Egan+ 2003)II/246 : 2MASS All-Sky Catalog of Point Sources (Cutri+ 2003)II/311 : WISE All-Sky Data Release (Cutri+ 2012)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/565/A30https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/565/A30http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/565/A30https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/565/A30https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/565/A30http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/565/A30GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/565/A30/table5 (Candidate YSOs obtained from the 2MASS (II/246) and MSX (V/114) point source catalogs)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/565/A30/table5?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/565/A30/table5?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/565/A30/table5?GETtext/xml+votable180.050000true165.294875-59.82052780.005555555555555556Cone search capability for table J/A+A/565/A30/table6 (Candidate YSOs obtained from the WISE point source source (II/311))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/565/A30/table6?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/565/A30/table6?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/565/A30/table6?GETtext/xml+votable180.050000true165.273875-59.79819440.0055555555555555566/379327.947616174868663e-21 1.7003137259100215e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/565/A30?format=asciiInfrareddefaultJ/A+A/565/A30/table5Candidate YSOs obtained from the 2MASS (II/246) and MSX (V/114) point source catalogsrecnoRecord number assigned by the VizieR team.
