cds-question@unistra.frmilky-way-galaxyopen-star-clustersgalaxy-classification-systemsIn this paper, we investigate the nature of 27 star cluster candidates, most of them projected towards the Galactic anticentre. We derive fundamental parameters for 20 confirmed clusters, among these 7 are new identifications. Four of the remaining are uncertain cases that require deeper photometry to establish their nature, and four are probably field fluctuations. In addition, we provide a partial census of the open clusters towards the Galactic anticentre. We also include in this study some interesting objects outside the anticentre region, in the second and third Galactic quadrants, mainly in the Perseus and outer arms. These clusters confirm the extension of the outer arm along the third quadrant. We also point out that the embedded cluster FSR 486, at a distance of 7.2+/-1.3kpc from the Sun, is projected on the line of sight of the Local Group irregular dwarf galaxy IC 10. Thus, part of the unusual properties of IC 10 may be explained by a Galactic contamination. We point out the importance of embedded clusters in tracing the spiral structure.2013MNRAS.432.3349Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/432/3349CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/432/3349https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/432/3349http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/432/3349https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/432/3349https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/432/3349http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/432/3349GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/432/3349/table2 (Derived fundamental parameters for confirmed star clusters in the present study)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/432/3349/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/432/3349/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/432/3349/table2?GETtext/xml+votable180.050000true61.49166751.1019440.005555555555555556Cone search capability for table J/MNRAS/432/3349/tableb1 (Derived fundamental parameters for clusters in Papers I, II, and III)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/432/3349/tableb1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/432/3349/tableb1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/432/3349/tableb1?GETtext/xml+votable180.050000true85.212535.6388890.0055555555555555566/1293 1297 1299 1335 1358 1423 1436 1781 1848 3042 6154 6676 21519 21550 22060 22121 22124 23671 23727 23763 23765 23850 23938 23941 23972 23976 23994 23997 23999 24120 24162 24181 24240 24256 24359 24361 24367 24427 24439 24450 24470 24476 24496-24497 24499 24554https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/432/3349?format=asciiOpticaldefaultJ/MNRAS/432/3349/table2Derived fundamental parameters for confirmed star clusters in the present studySimbadNameSimbad column added by the CDSmeta.idcharrecnoRecord number assigned by the VizieR team.
