cds-question@unistra.fryoung-stellar-objectsinfrared-sourcesinfrared-photometrymillimeter-astronomyphotometrysubmillimeter-astronomyWe report the discovery of a new young stellar cluster in the outer Galaxy located at the position of an IRAS Point Source Catalog source that has been previously misidentified as an external galaxy. The cluster is seen in our near-infrared imaging towards IRAS 04186+5143 and in archive Spitzer images confirming the young stellar nature of the sources detected. There is also evidence of subclustering seen in the spatial distributions of young stars and of gas and dust. Near- and mid-infrared photometry indicates that the stars exhibit colours compatible with reddening by interstellar and circumstellar dust and are likely to be low- and intermediate-mass young stellar objects (YSOs) with a large proportion of Class I YSOs. Ammonia and CO lines were detected, with the CO emission well centred near the position of the richest part of the cluster. The velocity of the CO and NH3 lines indicates that the gas is Galactic and located at a distance of about 5.5kpc, in the outer Galaxy. Herschel data of this region characterize the dust environment of this molecular cloud core where the young cluster is embedded. We derive masses, luminosities, and temperatures of the molecular clumps where the young stars reside and discuss their evolutionary stages.2015MNRAS.452.1523Yhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/452/1523CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/452/1523https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/452/1523http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/452/1523https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/452/1523https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/452/1523http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/452/1523GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/452/1523/table1 (NOT sources towards IRAS 04186+5143)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/452/1523/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/452/1523/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/452/1523/table1?GETtext/xml+votable180.050000true65.5800451.837860.005555555555555556Cone search capability for table J/MNRAS/452/1523/table2 (Photometric data of Spitzer sources towards IRAS 04186+5143 having NOTCam counterparts)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/452/1523/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/452/1523/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/452/1523/table2?GETtext/xml+votable180.050000true65.5801251.85640.0055555555555555566/19322.483060040379131e-20 1.7798557115773645e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/452/1523?format=asciiInfraredRadiodefaultJ/MNRAS/452/1523/table1NOT sources towards IRAS 04186+5143recnoRecord number assigned by the VizieR team.
