cds-question@unistra.frsupernova-remnantsyoung-stellar-objectsinfrared-photometryWe have carried out ^12^CO, ^13^CO, and C^18^O observations toward the mixed morphology supernova remnant (SNR) IC 443. The observations cover a 1.5{deg}x1.5{deg} area and allow us to investigate the overall molecular environment of the remnant. Some northern and northeastern partial shell structure of CO gas is around the remnant. One of the partial shells, about 5' extending beyond the northeastern border of the remnant's bright radio shell, seems to just confine the faint radio halo. On the other hand, some faint CO clumps can be discerned along the eastern boundary of the faint remnant's radio halo. Connecting the eastern CO clumps, the northeastern partial shell structures, and the northern CO partial shell, we can see that a half molecular ring structure appears to surround the remnant. The LSR velocity of the half-ring structure is in the range of -5 km/s to -2 km/s, which is consistent with that of the -4 km/s molecular clouds. We suggest that the half-ring structure of the CO emission at V_LSR_~-4 km/s is associated with the SNR. The structures are possibly swept up by the stellar winds of SNR IC 443's massive progenitor. Based on the Wide-field Infrared Survey Explorer and the Two Micron All Sky Survey near-IR database, 62 young stellar object (YSO) candidates are selected within the radio halo of the remnant. These YSO candidates concentrated along the boundary of the remnant's bright radio shell are likely to be triggered by the stellar winds from the massive progenitor of SNR IC 443.2014ApJ...788..122Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/788/122CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVII/233 : The 2MASS Extended sources (IPAC/UMass, 2003-2006)II/311 : WISE All-Sky Data Release (Cutri+ 2012)II/327 : AKARI Far-Infrared Surveyor YSO catalog (Toth+, 2014)J/A+A/279/541 : Sub-mm observations of SNR IC 443 (van Dishoeck+ 1993)J/AJ/130/1145 : YSO near-infrared properties (Doppmann+, 2005)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/788/122https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/788/122http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/788/122https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/788/122https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/788/122http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/788/122GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/788/122/table3 (The Infrared Photometric Magnitudes of the YSO Candidates toward SNR IC 443)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/788/122/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/788/122/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/788/122/table3?GETtext/xml+votable180.050000true94.145958323.11258330.0055555555555555566/23993 23994 23995 23998 243378.157980699529898e-21 1.7003137259100215e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/788/122?format=asciiInfrareddefaultJ/ApJ/788/122/table3The Infrared Photometric Magnitudes of the YSO Candidates toward SNR IC 443recnoRecord number assigned by the VizieR team.
